It's a mature product. I would hope that that would count for
something. I've had enough corrupted subversion repositories that I'm
not crazy about the thought of using it in a production system. I
know I'm not the only person with this experience. Sure, you can keep
backups, and not really lose any work, but we're moving over because
we have uptime and availability problems, so lets not just create them

Uh, the Python community. Which is currently hosting a subversion
repository, so it doesn't seem like a stretch to imagine that
p4.python.org could exist just as easily.

Pardon me if I don't feel that I'd like to see a system in production
for a few weeks before we declare victory. The problems with this
kind of conversion can be very subtle, and very painful. I'm not
saying we shouldn't do this, I'm just saying that we should take an
appropriate measure of how much greener the grass really is on the
other side, and how much work we're willing to put in to make it that
