Sounds good to me. In general, it's easier to contribute first to https://github.com/jaraco/zipp and those changes can be readily merged into CPython. No worries, though. If these changes can be accepted here, I should be able to graft them onto jaraco/zipp as well, and thus provide the functionality for older Pythons.

At this point, Python 3.10 is frozen for features, which this change would be, so I'm updating the target version to 3.11.

That's right. It's meant to provide whatever consistency makes sense, but a subset of what's available on pathlib.Path. Happy to accept any contributions that would be useful.

Indeed, perhaps the documentation should be more clear about what is and isn't supported.
