This is not an engineering limitation; only an engineering problem to solve. My e-ink tablet can, and does, differentiate between three different types of swipes and taps, and it never does something I don’t ask it to.

Make it a 3-finger swipe. Hell, enable a confirmation dialog if you’re that uncertain about your ability to control it.

It’s like being afraid of accidentally running "sudo rm -rf /”, and just as easy to prevent accidents.
