Spectacular and congratulations for getting this through, Gavin.

This is a major milestone for us, but perhaps an also very significant
reference for Python 3 in general, alongside Mailman. I'm very proud of
witness our engineering team moving the Python ecosystem forward, so
may this victory glow upon all of you.
