That would break on the next update of xorg-x11-devel and/or
mesa-libGL-devel. Or ATrpms would need to keep patched up verisons of
these files to not have this happen, and it would be a race each time.

AFAIU the gl.h and libGL.so of mesa are upwards compatible to any
vendor specific library, e.g. that's what the GL API was for. You only
miss proprietary GL extensions, and that's in general a good thing,
otherwise your packages would require nvidia even on non-nvidia
hardware and would thus not work there.

There are two exeptions that deal with it properly, mplayer and
mythtv.
