There is no actual benefit in doing this.
Those additional prefixes are also there for a reason. They're maintained for backwards compatibility. 

This blog entry details (and/or touches on) at a high-level some of the changes made in 4.4 to improve performance. 
There will always be other areas that can be improved. There are always new test suites that can be tested against. Technology is constantly changing, both on the backend and in the user agent. If something was not mentioned in the blog entry, chances are it hasn't been changed. That doesn't mean it isn't something we should look at, it just means we haven't yet due to many reasons (time is one factor, but also sometimes changing an approach, such as how plugins are handled, is not a simple thing to do). I recommend posting suggestions of other areas you would like for us to look at in the appropriate feedback forum, so when we are planning 4.4.1 or 4.5 or 5.0 or any other future version, we can easily reference those ideas. Posting your suggestions here in blog entry comments will, unfortunately, likely result in those ideas being lost and forgotten.

Any work on changes to the plugin/application system of loading the entire PHP file in, doing a str_replace and EVALing the entire thing as doesn't using EVAL prevent opcache-specific optimizations from functioning? (haven't looked into it so not sure if true)

Are you planning removal of old property prefixes in 4.4 version?

This is absolutely no longer the recommended approach with HTTP/2 becoming mainstream, just FYI. Naturally there's always a balance, but I would recommend reading up some more on best ways to handle CSS/Javascript with HTTP/2 to learn more.

I've solved all the new features speed improvements using pagespeed module with Redis, on the high 90% in PageSpeed Insights, GTMetrix and all "A" in webpagetest. It's nice to see all these improvements addressed..
Some suggestions
Create different size avatars instead of using a 200x200 image on a 34x34 placeholder, there are CSS's that dynamically resize the originals, at the expense of bandwidth.
Articles images have the same problem, if I choose a 1000x1000 image, on the record list every article will download the ORIGINAL image and resize it with CSS... huge bandwidth usage.
Reduce the DOM tree...it's huge

We have many, many images in our gallery that are uploaded without geo-location data.  It would be nice to be able to add/edit geo-location info on the gallery record, overriding the geo-location information found (or not found) on the image itself.

Where is the most important feature: metadata geolocation?

Nice article. I sell ads directly to advertisers and premium membership to members. IPS is offering a lot of features to attract people buying subscriptions.

I have been using Adsense since 2005... and has worked well... I want to work on membership fee ..however the lack of payment gateway Integration for Indian customers have been an issue... I wanted for payUmoney....it has never been added.... I wish  additional payment gateways can do wonders for  my project 

What problems do you have? I use our site on my phone very frequently, and I don't have any problems.

Well, I said (or meant to say) it didn't look attractive on an iPhone.
I do like the looks of the community on my desktop computer.

The automatic moderation feature that was added to Invision Community 4.3 will help.

After all the great improvement done during 4.2 and 4.3 I think the "mobile front" is the main weakness of this software today

This topic has been coming up lately on virtually every forum. Facebook overtakes forums.
Facebook has its own terms and conditions. Many times they embarrass a member publicly by deleting their posts. In my city senior police officers have been put through this humiliation. 
In Facebook there is nothing like hierarchy. Once you comment on a six month old post the newer ones get buried deep down. if you want to own and hold your head high without the Fear of humiliation then forums are the way to go. 
Why are forums slowing down. Firstly its the cost of forum licence and hosting. Facebook is free. Secondly there is lot of trolling in forums. Facebook is very tough on this. The user can completely block a members if he is bothering him. If there are too many spam complaints the account is altogether closed down. 
In the long run the solution is to integrate forums and social media together as seamlessly as possible. Facebook Twitter Instagram and similar platforms need to be integrated into forums. Without this forums will slow down. 
To mention here Invision Power is not just a forum . It blog, Ecomm, Gallery and of-course with the right CMS coding a complete solution for an organisation. 
If they are able to deal with trollers IP is going nowhere for a longtime to come. 

Perfect, the member's PMs and "perPage" parameter is exactly what I've been waiting for to use in my app. Thanks!

Next time anybody suggests that the Invision Community team doesn't listen, send them to this article. There's so much here that I've seen people bring up over the past year. What an amazing product. You lovely, lovely people.

Member albums are already shown on their profile page.

Is there something specific you are looking for?
The navigation bar is available at the bottom of every page already:

 
I would suggest re-reading this blog entry, specifically the section labeled "New image navigation". We've done just what you requested in the next release (although the comments, ratings and other features are present in the lightbox in addition to the image itself).

This is already possible in 4.2 and will continue to be possible in 4.3.  You don't really need to fill in any image details during the upload process (unless you want to).  

Thank you for your answer. I missed the 100 limit fix, but I'm glad it has been improved. 
I really love how the gallery works, but talking from my experience (I owned  a Coppermine gallery since 2009): a lot of users are complaining about a low navigability across the pictures/album/categories. If you are scrolling a page while searching for a photo, it's really annoying that you have to go at the very top of the page to go back to the parent category.  A simple "back (level up)" button on the corner would be very useful. Also I really think you should allow users to skip the single picture page. We have so many pictures that we don't care much about comments and ratings. It would be much quicker to click on the preview of a picture and immediately open the picture, maybe on a popup.
As Joel said too, this is really something we miss very much since we left coppermine. We are re-uploading all our photos, and we are taking so much time to restore our albums. A simple improvement could be the option (maybe a checkbox) to skip the "details" box when you drag and drop your images. But in the end I really think an ftp connection for admins would simplify a lot everything.
 
Thank you for listening, I love the website and I really hope to see these simple improvements very soon!

Yes, that's supported already

There's no longer a harcoded max although it will probably depend upon your server.  I've tested up to 150 images on 4.3 Dev and it works fine, and tonight I plan on testing 500 or 1000 images.  

Do you mean fetching the location from EXIF data and showing a map? If so, we've supported that for a long time  

hallelujah!!! I've been silently praying for official Elasticsearch support! This is awesome news.
