I *think* the issue might be that our setuptools is too old to understand 
how to get project metadata from pyproject.toml (PEP 621).  This seems to 
indicate that it was added in setuptools 61.0.0:

https://setuptools.pypa.io/en/latest/userguide/pyproject_config.html

As a workaround, you might try to patch the metadata back into setup.cfg?
