If it's any consolation, I'm sighing along with you. :)

Two points:

1. Eventually, we should be able to drop PLAIN in a future revision of
the MTI technologies spec that we'll pull out of 3920bis in 1+ years.

2. The technology that the XMPP community uses for account registration
(XEP-0077) could benefit from an update, or even a replacement, and when
that work is completed I'd like to include a method by which a client
could register a key or cert with the server, thus smoothing the path
toward password-less authentication. IMHO that will be the best approach
in the longer term, instead of continually tweaking the password-based
methods. But that's a topic for another time...
