Reviewing #945824, I believe that even if we were eventually to overrule the Python maintainers on this, (i) the impact to users in the meantime is very low, and (ii) we are about to freeze, so it's unlikely we'd make any decision applying to bookworm. So I think we should leave this for the January meeting.
Agreed, this is not urgent. For the ongoing (or completed?) migration from 3.10 to 3.11, it's too late anyway. This is just about finding better migration strategies for future increments of the Python3 subversion. Joachim
