This "feature" has been deprecated for nearly two years now.

PyPI has not permitted uploading packages with invalid versions for even more years. The latest versions of pip should be rejecting/erroring out on wheels with such versions as well. The stricter metadata validation helps pip's dependency resolver's logic, along with helping the broader ecology avoid needing to deal with outside-of-standard tooling/behaviours.
