I guess technically this change should also be reviewed.

@jaraco feel free to request a review from me in such cases. I do tend to keep up with the ongoing work in the importlib_metadata and importlib_resources backports, so it might be easier for me to have a look compared to others.

An alternative to approving and merging this change could be to retroactively review and accept the changes for 3.13. I know we wouldn't normally apply such style-sync changes in an RC, but I also note that the AST doesn't change for the non-test code and changes only very modestly in tests. If @encukou would be okay with not applying this PR, that would be my preference.

I agree that, since the mistake is made, it's better to keep the style changes in than to revert them and re-introduce later.
@Yhg1s, do you agree?

Yes, the changes seem benign enough that there's no point in reverting and reapplying.
