For some reason I didn't receive Keith's message, so pardon me if
this has already been discussed.

All the hardware-design and standardization effort is going into the
programmable pipeline, which is certainly capable of accelerating
things like plane masks and per-component alpha.  (Don't know about
conjoint/disjoint compositing operators; haven't looked closely at
the definition.)
