Yeah, this is the kind of function I had in mind. Just that I think we should have an equivalent in the base packages.

I could not find this discussion, do you have any pointer?

Anyways, going deeper and deeper into the archives, I've found you made the same proposal almost exactly 10 years ago[1]! Oddly enough, it only prompted one reply at the time - has the rest of the discussion been removed from the archives because it was too rude? ;-) Should we reopen the debate now that some time has been spent without actions being taken on that front?
