Because Mesa has already been updated twice after the F20 release (9.2 -> 10.0 -> 10.1), I don't suppose updating to 10.2 or should cause a lot of issues.
Furthermore, as the only external mesa interface is OpenGL which is required to be stable anyway, there is no big risk involved.
All the internal interfaces (xorg, drm, ...) can be taken care by the distribution.

I did that, but rawhide is built with debug compiler options and therefore notably slower (at least phoronix benchmarks  say so) - and it usually breaks quite regulary.

I used that 10.1 repository before 10.1 was pushed to F20, it would be great if it would exist for 10.3 too.
I'll ask Felix, hopefully I'll be able to motivate him ;)
