I can see its use while debugging but I can't imagine it being of any
use in real ELisp code because it's much too blunt.
[ Personally I'd put a `--` in its name and/or add some blurb in the
docstring explaining it's only for debugging. ]

I don't see any reason why it needs to be in emacs-28.
It's not a bugfix and there's no hurry.
