Software rendering is a better bet if DKMS fails, as nouveau can cause
problems when dealing with (partially?) supported GPUs. I introduced that
change in bionic, but then I reverted that behaviour, also because it would
cause problems to hybrid graphics.

I don't think users relying on something that is broken should hold us
back. If anything, the fallback would cause users to file bug reports
(about graphics corruption, increased power consumption, etc.) against
nvidia, where these would be really nouveau's.
