[This bug is targeted to the upcoming trixie release]

The package build-depends or depends on python3-pkg-resources, which is
deprecated upstream. Details can be found at

https://setuptools.pypa.io/en/latest/pkg_resources.html

Use of pkg_resources is deprecated in favor of importlib.resources,
importlib.metadata and their backports (importlib_resources, importlib_metadata).
Some useful APIs are also provided by packaging (e.g. requirements and version
parsing). Users should refrain from new usage of pkg_resources and should work
to port to importlib-based solutions.

Python 3.12 in unstable provides both importlib_resources and
importlib_metadata, so no additional dependencies on those packages are needed.

Control: tags -1 + upstream moreinfo

mallard-ducktype (#1083471) is in a similar situation, although there don't
seem to be any third-party extensions to it packaged in Debian in practice,
so we might be able to get away with just deleting
/usr/lib/python3/dist-packages/mallard/ducktype/extensions/__init__.py and
hoping it doesn't break anything for unpackaged code.

I've asked upstream whether they are aware of third-party extensions that
are not packaged in Debian. I'm not intending to work on this further in
mallard-ducktype until there is an obvious correct thing to do.

Thanks,
