It won't work in Emacsen before Emacs 28, because it doesn't exist on
those systems. This idea would mean having to distribute the macro with
every package, with all the evils that would entail.

Please, can't we just halt all this and take stock? `interactive'
specifies how to call a lisp function interactively. This new stuff
being put it has nothing to do with the interactive call. It will foul
things up horribly.
Why can't this new feature be implemented without introducing
incompatibilities?
What am I missing?
