We shouldn't be hacking individual drivers to support whatever random
subset of userspace interfaces some system decides it wants to use -
that isn't making anyone happy.  If we want to have the ability to
customize which userspace interfaces appear it seems better to put that
in the core code so individual drivers don't need to worry about it,
from that point of view unifying the interfaces should be progress.
