There's definitely a lot to be said for having an initial phase where
only all-new test scripts get written in Python, and we shake out the
test infrastructure's teething problems in master only.  Once we feel
that we have that pretty much down, we could think about converting
the existing tests.  Based on this conversation, I think that step
will probably need to touch the back branches too.
