Nice work!
I think this makes a lot of sense (slightly biased), I agree that it
felt very wrong advising users to change permissions for uhid* when
they plugged in a gamepad, exposing a bunch of kernel functionality to
games that don't need it.
Having them Just-Work (tm) by default, while doing so in a clean and
safe way will help the experience a lot for gamers (and slacking
developers) alike! :-)
Some ports patches are still required if this goes in, as mentioned
devel/sdl2 at the very least, but the current situation as it stands
controllers already don't work out of the box.
thfr@ already has my ok and some general "good idea" from others, but
feedback is appreciated, as well as any tips for getting this ready to
go in.
