I do this myself - but it doesn't work well if the goal is to build up a set
of interoperable libraries across a community.

This could make a nice reference implementation.  It's not completely clear
to me whether you're also suggesting that this should be something that the
spec requires of implementations, though.  I don't see the need for it in
implementations that already provide a generic dispatch mechanism - it would
only add overhead.
