TODO: need to do something about the PYTHONWARNINGS failing.

Trac does not (officially) support Python 3.12 (I couldn't find a link to their Python support policy, but it's not listed in the trove classifiers on https://pypi.org/project/Trac/).

Because our Trac test suite is not super solid, I'm a bit hesitant with moving to 3.12.

Instead, I suggest we run Trac on 3.11 which will let us update Django 5.0 (and even 5.1).

In didn't know that. I added a comment in the Trac's issue 13774.

I agree.
