At the least, a precise specification of the desired behaviour, at the
best, code that implements both server and useful client using the new
behaviour. Leaving the current semantics untouched means we don't have
to worry about compatibility though, even if the current mechanism are
horribly broken.

And, I'm not worried about impolitic usage here. The current
specification and implementation must both stand on their merits, if
they have none, we should rewrite the spec to guide developers towards
more useful designs.
