PS: in French there's a word: "acquit de conscience"', I can't translate, but this "from trytond.tools import timezone as tz" was bugging me and indeed "pytz" is needed only to be recommended when python3 < 3.9
I think that even backports to oldoldstable should be perfectly fine as Recommended packages never get autoremoved on upgrade unless someone used ultra-agressive apt/unattended-upgrades settings.
