The Python packaging guidelines ask for parity with PyPI: https://docs.fedoraproject.org/en-US/packaging-guidelines/Python/#_pypi_parity
PyPI tooling is such that one may get conflicts: https://github.com/pypi/warehouse/issues/19720
Is it reasonable to update the packaging guidelines for python to indicate this and allow for conflicts in such cases?
https://github.com/pypi/warehouse/issues/19720 is about file conflicts.
The PyPi parity is about package names in Python metadata.
