These questions ask things about the design choices and decisions involved in making blender to which probably only the developers can give a complete answer.
I know that this probably is out of our current scope:
The Blender Stack Exchange site is for people who use Blender to create 3D graphics, animations, or games.
Since in the past these kinds of questions seem to be asked in places like the mailing list and IRC, it's hard to find existing answers.
If these questions were allowed on SE, they could stick around and not be buried in some long lost mailing list thread.
Should we expand our scope to allow more development oriented questions?
What do the developer users think of this?
