I would love it if the standard test runner could output subunit (by
bundling the python serialisation component ideally ;P). However
processing subunit streams for filtering/listing/reporting etc isn't a
core python task - and subunit is a multilanguage project; I'd hesitate
to roll the rest of it into python's standard library. Also, note that
the standard library *does* support subunit today, because subunit is
compatible with the standard library API: you just substitute in an
appropriate TestResult or TestCase (for serialisation or
deserialisation).

If I'm translating correctly you mean '75% of bzrlib.tests.__init__'
should be in the upstream runner.

I think thats probably high, but certainly a lot would be nice to
offload. I see projects like testscenarios as a good way to take ideas
we've proven in bzrlib and make them accessible to others. If they
survive in the wild, we can then start proposing them for the standard
library.
