Nice to always learn something from the detailed description on the PRs.
Otherwise I am only confused a bit from the codeQL comments and the warnings replacement for pytest.warn. It is much less readable.
But please go for it! 👍

[maxfischer2781]

@eileen-kuehn I think you are right about the warnings test. I've expanded the comment a bit and linked to the docs now, hopefully that makes it less obscure.

[eileen-kuehn]

This may help a lot, thanks! 👍

Sorry for the late approval. I was distracted by some puppy eyes. 🥺
Looks good to me, and the tests 👍
