This is my problem when I post, what I meant to say is if someone gets a custom made plugin or application. For example, If you add a feature to "Forms" then yes, it should be supported. However, if someone hires you, or another developer for that matter for a unique plugin or application then that is when what I posted comes in to play.
I am seriously bad at posting as people seem to read what I say wrong. I am working on it.
