I think that to get some traction on this issue, that it needs to be brought up and discussed at one the animation and rigging meetings. Not sure if you want to do that yourself or to get someone like @Orestiskon or Jason Schleifer who were at the last meeting and who have used packages other than Blender.
I think that the main devs (who have possibly only ever used Blender for 3d) don’t really understand where we are coming from on this issue, and it needs to be hashed out in a discussion.
