Sorry, I missed where you mentioned that, but your point stands.

So, in that case, what I'm really advocating is: let's change it to
return a *better* representation, and update all the callers in Emacs.
(I doubt there are many callers outside the Emacs distribution, but
even if there are, it's still worth going through this pain once so we
have an extensible type from now on.)
