b) would it be acceptable if done properly? (cmd line option to enable, avoiding duplicate/wrong events?)Well, for one, you shouldn't be using a timer, all the debouncing can be done by math on the event timestamps.Not... really, right? You need to send an release some time after button indicates release if bounce did not happen. It is similar to autorepeat needing a timer.
You can send the first release and ignore all presses and releases in a time window after that.
Let me gain some experience with the patch. I don't think hardware does as heavy debouncing as you describe.
Microswitches vibrate significantly when clicked. Without hardware debouncing, you'd have many clicks instead of one even on a new mouse. -- Vojtech Pavlik
