Updating Flask to 3.x?

[Carsten Schoenert <c.schoenert@t-online.de>]

Hi,

the Flask team released Flask and the depending package Werkzeug 3.0.0 
on 2023-09-30.

Since Thomas Goirand did the last update of Flask to 2.2.x nearly one 
year ago in preparation for the Bookworm release I've talked with Thomas 
recently about updating Flask and depending packages again so we can get 
Flask 3.x into the archive.
Thomas pointed out he will not have time to work on Flask 3 and some 
depending packages in the near future.

I usual try to keep an eye on some Flask related packages as we use them 
on my day job. A few of them have now RC issues and are already kicked 
out of testing. Solving these bug reports are now mostly depending on a 
newer Flask version or at least it would be more useful to move over to 
a recent Flask version.

Given we are now short before the X-mas days and I will have some more 
time to look at some packages I'm willing to push things further.

I've started on Flask and werkzeug packages yesterday and basically 
there are no big issues to get these packages updated.
If no objections are raised I intend to upload recent versions of 
python-flask and python-werkzeug to experimental next week.

Once happen we will see through

https://qa.debian.org/excuses.php?experimental=1&package=python-werkzeug
https://qa.debian.org/excuses.php?experimental=1&package=flask

which packages would prevent a migration later due build or test failures.

Following a simple list of reverse deps for the resulting binary 
packages. Any help, suggestion or useful hint in maintaining this Flask 
update is really appreciated!

@Thomas
Do you agree on my plan? Or do you have reasons to wait a bit more with 
uploading Flask and Werkzeug to experimental?
