The change itself looks good to me now. The last item we need is a NEWS entry, as described in https://devguide.python.org/committing/#what-s-new-and-news-entries, which can be created using the blurb tool at https://pypi.org/project/blurb/
Alternatively, just comment below and I can add a suitable blurb entry for you (that may take a bit longer, though)

@ncoghlan I have added the News entry. Thanks for reviewing! |
