Nvm about wobbliness — perhaps movement events that removed by hysteresis not
being shown in libinput debug-events.

Regarding your question to experiment — no, I don't see any difference, e.g.
2-fingers touch still results in 1-finger + 2-fingers tuple. I have yet to see
the problem of skipping the touches — but, I think, we determined that it's
result of motion by wobbly touchpad, and wobbliness persist, so not sure if
there's anything more to see.
