Judging by the number of packages that include 'mesa' as an input, it
won't be so easy.  Search for ",mesa" in gnu/packages/*.scm, and see the
output of "guix refresh -l mesa".  The xf86-video-* packages include
'mesa' as input, and many other packages as well.

I won't block this, but I will take this opportunity to mention that for
those of us who wish to build GuixSD from source code on our own
machines, life is becoming increasingly uncomfortable as more and more
optional features are added to our core packages.  We are on a
trajectory to leave that set of users behind, as we cater primarily to
the majority who use the latest Intel machines and don't worry about the
security of either the Intel Management Engine or our build farm.
