This is exactly the sort of contrivance I was talking about.  Sure, we
can prove, mathematically, that mandatory-only produces fewer points
of articulation, but are you aware of a case where this results in a
real problem?

The idea of optional constraints makes even less sense in light of
Harald's UI proposal.  If we grant access to all input devices by
convention, then this problem becomes academic.

I don't care to solve purely academic problems...at least when I'm on the clock.
