Mostly wishlist and information I've uncovered looking into this.
The latest version of flask in Debian is 2.2.2-2, while Ubuntu Lunar has 2.0.3-1ubuntu1. I haven't looked in detail on the functional changes, but it would be nice to upgrade plus I believe it would resolve bug 2000013. And it is a small delta, so should be rather straight forward to reapply it on the latest version.
First the good news:
python3-asgiref is now in main, so no longer need to be moved around in the delta.
(python3-dotenv is still in universe, no change there)
The bad news:
flask has a new build dependency: python3-tomli. This is in universe, which as I understand is unavailable when building packages in main. So I don't know the preferred course of action for that one, whether it needs a MIR before upgrading flask or finding a different workaround.
These are my findings, and I believe once the build dependency have been dealt with I would expect the rest of the merge to be straight forward.
Thanks for the great analysis! Sorry, I saw this only after merging flask to unblock the python3-werkzeug migration.
