Well,

what about the point that there are different vendors out there
supplying a libGL, that for some reason uses a totally different
dispatch mechanism ? IHMO, the whole discussion drifts off to much
into specific implementation details.

>From ausers prespective, I would guess that it's way more important to
make porting easier (yes, this also means from and to windows). Having
a glXGetProcAddress() that is essentially compatible with a
wglGetProcAddress() is a very important thing to have.
