In python/importlib_metadata#377, Benoit reports that the "_normalized_name" of importlib_metadata and importlib.metadata is including an extraneous .egg. This issue means that in environments where both .dist-info and .egg-info exist for a package, they're not deduplicated and the entry points are returned for both. The scenario is common and problemmatic as evidenced by other bug reports (python/importlib_metadata#410, python/importlib_metadata#413). The fix, added in importlib_metadata 4.11.4, has been ported to Python 3.11.1 in #98875, but the fix should also be backported to Python 3.10.
