In the specific case of evdev vs. kbd/mouse, yes.  It also causes people
to get really, really confused as to why they have all these unused
devices around.  'Ah well, you see, we expect the useful ones to fail,
so we just loaded these fallbacks assuming that hotplug will fail, and
on the off chance it somehow succeeded, they'd just kick the fallbacks
out anyway.'
