Actually I would do it the other way around.  You can't really explain to
your UTF-8 using users "you should use that older client instead of this
newer one to make your login work".  And some day you'll have to switch to
UTF-8 anyway.

s/flexible/vague/ :-)

The consensus on the imap-protocol list, and particularly the message you
refer to, seems to be "we should replace ASCII with UTF-8 in the spec".
