Abstract 'follow' method out of controller

[Marcher Technologies]

In the vein of this: 

And in the  train of thought of avoiding doing this:

Can the hunk of code that actually 'follows' and 'unfollows' things in IPS\core\modules\front\system\notifications be abstracted out to actually be on the item/node object, or anywhere it could actually be reused?

The above reason is not the first time I have needed to control follow status dynamically, and currently such strays extremely close to a direct copy-past of a large chunk of code that is not desired to be maintained by me, and falls foul of the license agreement.

I will raise your request for consideration.
