This whole discussion merely confirms my suspicion that we've put way
too little thought into a) what repository UUIDs are good for, and b)
how to implement them.

Givent that, -1 on this change until we have a clear design, including
documenting and solving these corner-case side effects, outlining an
upgrade path, etc. ad nauseam. If that means we don't get UUIDs in the
repository for another month or two or six, so be it.

As I said elsewhere, we can't continue with this hack-and-test approach
to core repository/filesystem features. If we want to see a 1.0 in the
next three months, we have to stabilize things now. I'd be much happier
without repository UUIDs in 1.0 that with a design/implementation that
doesn't address even the first-order side effects satisfactorily.
