--- Comment #2 from John C Klensin <john+w3cbugs@jck.com> ---
Mathias, 
Yes, but let's be a little careful.  For better or worse, the bug 15489 and
18162 threads are ultimately about an enhancement to handle email addresses
that SMTP (as well as older versions of HTML) did ot anticipate, namely those
that contain non-ASCII characters.  If those characters are entirely in the
domain part of the address, there is an obvious workaround by using A-labels
(the Unicode strings encoded via the Punycode algorithm into an
ASCII-compatible form)  Whether that is desirable or not is a UI problem and
may be an operating system one (See RFC 6055).

This particular problem, as far as I can tell, is a terminology one that was
wrong but that appeared mostly harmless until it led to confusion about
appropriate test cases and the like.  There is no required substantive change
to implementations or extension, just a need to correct the description to
avoid confusion or worse.  It now appears to be worth the effort to just fix
the language and be done with it.
