I think the problem here is more to do with where we started than where
we're going or how we got there - things have been glued together or
happened to work in ways that mean I'm not sure we reasonably understand
the situation we started from or all the requirements it has.  As you
say I'm not sure anything beyond throwing the API away and starting
afresh would really help here, but that's not really how we tend to do
things for a bunch of very good reasons.
