I appreciate the flexibility inherent in that approach, but personally,
I'd be frightened of such a system.  I sometimes have problems figuring
out which directives are active in the current system, if I had to
reason about dozens of priority levels I think it'd be worse.

I don't quite follow the "for the rest of us" part.  Will you expand on
that?
