Most of those python2 packages are needed by the test suite still. We still claim to support upgrading from older versions of MAAS that used south, and which needs python2.

I'm guessing that we could remove the south migrations now, though, since anyone with such old version still have go through xenial to upgrade, and the xenial version would handle the south migrations (at least in theory).

But without removing the south migrations, this branch can't land. FWIW, this is the test failure:
