mostly, it's largely a matter of not exporting information that doesn't need
to be exported. at least with touchpads libinput does a few tricks and
changes the number of touches available (not yet at runtime, but who knows)
- once we start exporting this we're a lot more limited in what we can do
internally to work around broken devices.

Main question is though: what do you need this value for?
