Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

This change is simple enough, and I have no strong objections, although I do not see an immerse need of this feature.

Please add a What's New entry.

While we are at it, what about that flaky MacOS tkinter test? Can I just ignore it? Is there a place to re-run only it when it fails?

Core developers can re-run failing jobs to ignore flaky issues. The tkinter failure is a flaky test, it's unrelated to your change.
