string is intentionally not part of the signature.

Essentially the same as #43232. Just because it's possible to pass string in some cases does not make it generally valid, safe or advisable.

Edit: I guess there are some rare valid cases? Still seems bad to me tho. #52124 (comment)

It's not clear why you want this beyond the changes that already happened at #52124. "Sample Code" should be the kind of user-land code that you want to be accepted, not your proposed diff.
