Not necessarily.  Although I share your concern about
Emacs promulgating curly quotes, there is a real usage
problem akin to "typos": users copying text, including
Lisp code, from a web page or elsewhere, and pasting
it into Emacs as code to be evaluated at some point.

If the source of the copy has already changed simple
apostrophe to a curly quote (as one example) then that's
what gets passed to Emacs.  The person copy+pasting
may well have no clue about just which characters are
being copied.
