Just something that was bugging me a bit :D I hope this won't be an issue regarding 4.x compatibility?

It may be worth checking how this affect Sphinx 4-, as Python 3.10 and 3.9 use Sphinx 3.4.3.

Can we achieve compatibility without deleting this?

It may be worth checking how this affect Sphinx 4-, as Python 3.10 and 3.9 use Sphinx 3.4.3.

Note I'm proposing pinning python-docs-theme for the 3.10 and 3.11 branches in python/cpython#129576. We already pinned for the 3.8 and 3.9 branches in python/cpython#115349. However in the absence of that, this PR should be tested with 3.4.3, 7.2.6, and 8.1.3 ([ref]).

I'll test it later today or tomorrow (at Fosdem currently)

In addition to 8.1.3, I checked with 3.4.3 and 7.2.6 and both work as well :)
