Then belay my 16-bit ramblings.  I'm probably a bit naive in thinking a
new attribute would be passed along by enough transits to be useful; an
"adopt this incompatible protocol or become an island" approach may well
be needed.

I still have to wonder if some leaf optimizations are possible.  Perhaps
an incompatible protocol would leave more implementation wiggle room.
