I believe these questions are already covered by

"+Other userspace is only admissible if exposing a given feature through OpenGL
or
+OpenGL ES would result in a technically unsound design, incomplete driver or
+an implementation which isn't useful in real world usage."

If OpenGL needs the interface, then you need a Mesa implementation.
It's time for you to work with the community to build that or get it
built.  Or, in AMD's case, work with the Mesa developers that you
already employ.

If OpenGL doesn't need it, but Vulkan needs it, then we don't have a
clear policy in place, and this patch doesn't change that.  I would
personally say that AMDVLK doesn't qualify given that as far as I know
there is not open review of proposed patches to the project as they're
being developed.
