I’m 100% OK with such a change. I do not have time to implement, test, and document, but I can help with the review.

Issue created :

I’ve also created an issue for the buildbot as well :

As for the API guidelines, I suggest notifying those who do this via the MRs that break it and tell/ask them not to do it anymore. I don’t know how many read this board.

And use actual deprecation instead !
