It's really not much: Middle button emu, translation/acceleration, ...
The point being their guts are exposed via input properties. Most cases
are trivial, which reads 'fairly safe given properly aligned writes are
atomic'. For the rest, there should be provisions (like suppressing
input processing) or a clear statement against complicated stuff in
props. At least, that's my opinion.
