bkchem requires the pmw module. But it ships neither a dependency on
python3-pmw, nor has python3-pmw been uploaded to the archive yet.

There is a working module though:
https://pypi.org/project/Pmw-py3/

The bkchem package is functional without a separate python3-pmw package as it
is carrying its own vendored version of pmw:

$ dpkg -L bkchem|grep -i pmw
/usr/share/bkchem/bkchem/Pmw.py
/usr/share/bkchem/bkchem/PmwBlt.py
/usr/share/bkchem/bkchem/PmwColor.py

Bundling pmw into the application is one of the intended modes of use of this
module, with the pmw sources including a "bundlepmw.py" script that generates
the files included in bkchem.

For bkchem we can then either:

1. carefully check through the quite large divergence between pmw upstream and
 bkchem's vendored version of pmw (some 41 commits in bkchem git)
2. package python3-pmw
3. wait for it to go through NEW
4. devendor pmw (note that is not just a matter of deleting the files)
5. depend on the python3-pmw package instead

or

1. do nothing to bkchem. (that doesn't preclude updating python3-pmw for
#886617 anyway, just that bkchem wouldn't use it)


There is one other potential user of a python3-pmw package in Debian and that
is the auto-07p package. Like bkchem, the auto-07p git history shows
modification of the bundled pmw making devendoring hard.
