Hmm, simple ORs could be handled via multiple entries for the same PC.  But
obviously my idea doesn't handle more complex ops.

Hmm, I'm trying to think of a non-watch case which wouldn't / couldn't be PC
based.  Maybe some SP stuff.  But the 6502 is so register constrained that I
can't image triggering a breakpoint without some constraints on PC.

Even if you were to allow arbitrary breakpoint conditions, I suspect that
90+% of the use would be for very constrained cases anyway.
