It's not about affecting other modes, but the fact that quoting code in
elisp docstrings would only be reasonably doable from Emacs' elisp mode,
since curved quotes aren't easy to type.  That could be a problem in
cases like answering elisp question on SE, in an email, etc.

I don't think it's worth it to make it unnecessarily hard to write
elisp docstrings anywhere else than in emacs-lisp-mode in Emacs.

It might look like I insist, but something `like-this` looks more than
ok to me:

- it is a really common practice nowadays and most people understand
  what it means.  Many projects use Markdown in their README for
  example;

- it doesn't require to use a special character (understand characters
  that one cannot easily type on a QWERTY keyboard);

- it fixes the "unbalanced" quotes issue that you raised as well as
  using a curved single quote.


But again, I don't see the need for a change at all, and I have never
seen how quoted code looked like in older terminals.

Cheers,
Nico
