Wouldn't this be automatically included with the next distutils sync ?
https://setuptools.pypa.io/en/latest/development/developer-guide.html#code-conventions-and-other-practices

the setuptools/_distutils directory [...] should not be modified directly when contributing to the setuptools project. Instead, this directory is maintained as a separated project [...], and periodically merged into setuptools.

Oh, I missed that part of the contributing guide.

Let me know if I can help out somehow in doing that. I can probably pull in all the other changes in the distutils repo if necessary. Otherwise, let's close this PR.
