Just to mention this:

the reason logind applies the timeout and doesn't immediately react to
lid changes is to be friendly to users, if they quickly close and
reopen the lid. It's not supposed to be a work-around around broken
input drivers.

I am very sure that input drivers shouldn't lie to userspace. If you
don't know the state of the switch, then you don#t know it, and should
clarify that to userspace somehow.
