I think there is difference between ”not necessary to write non-UTF-8 
CSS”, on one side, and ”not having to use the CSS @charset”, on the 
other side.

Namely: If you *do* have a site where the HTML files use a legacy 
encoding, you could still switch the CSS files to UTF-8 - without 
simultaneously switching the HTML files to UTF-8, as long as the 
encoding is declared via @charset rule (or via HTTP).

Thus, with regard the situation that Richard described:

Then, for such situations, it could perhaps be of help knowing that 
they could start their switch to UTF-8 by switching the CSS to UTF-8 
first and that @charset could be of help for that, since the @charset 
"UTF-8" would make the CSS work even if the CSS makes use of non-ASCII 
selectors.

HTML(5) permits <meta charset="UTF-8"/> in XHTML, as long as it 
specifies "UTF-8". And it seems like not recommending @charset in CSS, 
except when it says "UTF-8", could be a similarly decent rule.
