I am thinking that introducing such a 'tip' unit might be the way to go,
without defining it as a hard ratio of any existing unit, nor as a hard
coded physical distance, but something left up to the UA / user
configuration.

Just like authors should expect the 1rem to match be sized to whatever the
default font size should be for that particular user in that particular
environment for things to be readable, they could expect 1tip to be sized
just right for things to be touchable.
