I had a look at the remaining ones, and updated the bug reports with patches and
information about new upstream versions:

>>     https://bugs.debian.org/973167 src:ufonormalizer

can be worked around, by re-introducing the plistlib.Data class.

disabling the _dummy_thread tests fixes these.

solved by new upstream, Dimitry wants to have a look

That leaves

 - python-kubernetes, complex packaging of new upstream.
   Thomas wants to have a look.

 - pylint, upstream talking about fixing three
   remaining test cases.


So I'll ask the release team for a slot for the python3-defaults 3.9.0-2 upload
to unstable.
