I hoped we could just add a distutils\..* entry to the 3.11 allowlist. But that's not sufficient, because stubtest still complains about all sorts of unused allowlist entries from the py3_common allowlist. So those need to be removed from the py3_common allowlist and pasted into the {3.10, 3.9, 3.8, 3.7} allowlists instead.

In case it's useful in the future, there's the x -> (x)? trick if you want to avoid unused allowlist errors. A hidden feature of stubtest is that it will not complain about an unused allowlist entry if it's a regex that could match the empty string. In this case, we could have used it to mark all the distutils things in py3_common.txt.

Yah, I considered this, but it felt vaguely immoral for this situation somehow ¯\_(ツ)_/¯
