Sorry if the answer was unclear.  Under the current proposal, a library 
of Emacs Lisp code can choose either style, by using the style in its 
doc strings.  By default, the user will see the library's style.  So 
yes, libraries can choose.  As Eli mentioned, there's a mechanism in 
Emacs to display Unicode characters using approximations on less-capable 
displays, and in that sense the user will be able override a library 
that prefers curved quotes.

No, not at all.  Libraries that want to remain easily-editable in older 
versions of Emacs can continue to quote `like this'; their users and 
developers won't need to fork Emacs.

It's not a pseudo argument.  Appearance matters, and the older style is 
off-putting on today's displays.  This is why the GNU coding standards 
recommend against quoting `like this'.  See:
