One comment I have on the section regarding touchpad gestures converted into
key events - do we have specific use-cases here where this is already done?

Gestures are generally nontrivial once you get past the few that everyone
knows (tap/pinch/swipe). The quality of many touchpads makes those gestures
hard enough, let alone anything more fine-grained than that.
An attempt to make touchpad input work for logograms would have some overlap
here but that fizzled out too.

I'd like to hear some specific cases here to get a grasp of what the
requirements are, thanks.

Cheers,
