Sorry, @bharel and @vsajip, I could not cleanly backport this to 3.11 due to a conflict.
Please backport using cherry_picker on command line.

Sorry @bharel and @vsajip, I had trouble checking out the 3.10 backport branch.
Please retry by removing and re-adding the "needs backport to 3.10" label.
Alternatively, you can backport using cherry_picker on the command line.

Actually 3.10 is now security-fixes only.

@vsajip Thanks for the merge 😄
Why are we adding to 3.11? Is this technically a bug fix or a new feature? I'm guessing you took it as a bug fix, but I saw it as a feature. Keep in mind that the Python version I've set in the docs reference 3.12, and must be changed to 3.11.3/4 if so.

[vsajip]

You're right, it is a new feature - I wasn't thinking clearly. Let's leave it and not backport.
