Can we cut another release (I'm interested for Python 3.10) that includes this?

[pfmoore]

No, sorry, Python 3.10 is now in security fix only mode - see the release schedule.

@zooba any chance we might backport this to 3.11? We're 1 version behind at work, and forced to use windows, and while using Git bash or Msys and creating venvs, doing python -m pip install <something> with a venv activated installs the packages in the main python site-packages instead.

I'd appreciate for it to work as expected :)

Backporting to 3.11 is probably okay, but we need a new PR without the additional change to the batch file.

If you (or someone else) creates one, target 3.11 and put [3.11] at the start of the PR name and (GH-103325) at the end.
