What expectations?  

With respect, Info didn’t use different face for quoted text for ages.  Did the 
expectations of the readers change all of a sudden?

And if it’s just *your* expectation and your preference, doesn’t it belong into 
your personal "init.el" then?

Oh, well, they are of quite some importance, since they happen to demonstrate 
what this is all about:  That courier is not consistently of good quality, and 
can be a very poor font on some systems.

I’m not sure whether I can follow.  I mean, I could add an arbitrary “good” 
font as alias for "courier" myself, but then I could just customize the 
"Info-quoted" face right away (which is what I’m doing currently).

And if the system can’t provide proper courier font or alias, how could Emacs 
do any better?
