Thread:User talk:Sumanah/Resources for non-WMF extension developers?

I've noticed there is a wealth of resources and support for core developers and for extensions being submitted for deployment on WMF wikis, but not as much for folks running independent wikis or developing extensions for non-WMF wikis. I was curious if that was a common perception, if there are resources I may be missing, if there are any plans in the works I could assist with or help motivate along. :) For example, it would be great if there was a similar review process for extensions not seeking deployment on WMF wikis, some sort of system for folks with commit access to maybe access test installations of the most recent versions of MW to provide more accurate compatibility information, more resources specific to the diversity of installations developers may face, etc.  Just a thought - thanks!
