Hi Matthias,

I don't know if that was on purpose, but you happen to upload Python 3.9
in Unstable the day OpenStack was released. I then rebuilt all of
OpenStack to upload from Experimental to Unstable, and to my surprise,
it went very well (note: all packages in the OpenStack team are running
unit tests at build time on all available Python versions). Only 2
issues happened multiple times:
- base64.{en,de}codestring removal (easy fix: s/string/bytes/)
- Threading.isAlive removal (easy fix too: s/isAlive/is_alive/)

This happened

This is on a set of 200+ packages which I manually rebuilt.

I do expect that there will be more packages with the same issue, so
it'd be nice to have all Python-using packages rebuilt. As Lucas
Nussbaum proposed such a service, should we ask him to do such a massive
rebuilt? Or maybe you have other plans?

Cheers,
