libinput does have a detection code — otherwise how could it "remove" wobbling.
Per my understanding it's detection of a bunch of micromovements — ones that
very quick and very close.

By "keeping finger still" I don't necessarily mean having it really still, I
rather opposing it to a very quick stroke across the touchpad, which, I'm
guessing, indeed might not wobble.
