Actually, I guess I should add here that the Schematron was never
meant to be used on its own. It was always seen as an add-on to a more
traditional schema language, since as you say doing a tight and
complete schema with the Schematron is usually just way too much work.

None of this contradicts your point in any way, of course, but part of
what DSDL is about is allowing people to combine RELAX-NG and the
Schematron so that they can have it both ways.
