Thats the plan, some distros have to keep shipping older drivers, but
also want to ship newer drivers.

the libGL -> driver interface is a lot more standard than the internal
mesa<->driver interfaces, and are not the same thing.

Removing the drivers allowed major simplification of mesa internal
interfaces not the GL->driver interface.

It doesn't save any space on the git server since git holds all the
history ever.
