We could somehow provide a way (maybe an xorg-service option) to rewrite
the package graph so that it uses mesa-minimal.  WDYT?

This is true, but it’s a problem that concerns GNU/Linux in general;
I don’t think Guix is really special in this regard.

I mean, in the good ol’ GCC 2.95 and GTK+ 2.x days, when D-Bus and its
friends didn’t exist, there was much less to build, right?  :-)
