Chris B gave what I think is a good reply to this, but feel free to
ask if you have further questions.  I think it's important that we
reach some consensus on why this a good idea on technical grounds
without anyone feeling like the decision is made opaquely in some back
room, so please raise any doubts or concerns you may still have, and
we'll do our best to address them.
