I'd rather declare the former obsolete
So would I, but there is some sentiment in this thread for supporting the old ASCII-only form. And even if we want to obsolete the old form we'll need to support it for a while, to give users time to switch.
‘foo-bar’ is ambiguous.
Not in current Emacs. It's a quoted symbol when it appears in a docstring, just as `foo-bar' is a quoted symbol. Of course there are exceptions when the quotes are themselves escaped, but similar exceptions apply to ASCII quotes.
In practice, curved quotes are a bit less ambiguous than ASCII quotes, because one can easily use them to quote any ASCII-only Lisp code, and this is something that ASCII quotes can't do.
