Thanks for the initiative!  It looks good, on first sight.  One question
I have is this: does it rely on the Python package having been built
with setuptools/distutils?  The Python world is moving toward a
plurality of PEP 517 compliant build systems; any idea if the checker
will continue working for these new packages?

We have currently only one such package in our collection, on
core-updates.  It's python-isort, added with commit
812a2931de553d12c01b0a4d53d03613b09adaaf on the core-updates branch.

Thank you,

Maxim
