Agreed. But based on the quick count I just did, we are also going to
need to deal with a lot of cases of modifying an existing test. If
the "same" test is written completely differently in master, that's
going to be super painful.

I'm starting to think that we'd thank ourselves in the long run
if we did do the conversion in all branches at once.
