I don't recall one and I can think of arguments on both sides of the
fence.  It would be nice if users could switch between a 0.22-fixes and
0.22-plus without having to up/down-grade their database.  That may
restrict what items can be backported though, so we might have to
take that on a case by case basis.  If any DB updates are carried over
to 0.22-plus, they should be exactly as they are in trunk, and they
should not break backwards (ie, 0.22-fixes) compatibility.  It would
be nice to have the ability to downgrade the DB, but I don't see that
as a possiblity in every case with the amount of data we have that changes.
The downgrade would also have to be in the newer code which makes it a
bit harder.

Maybe we need a 0.22-plus which is DB compatible with 0.22-fixes as well
as a 0.22-plusplus which is DB compatible with trunk. :)
