Using cleartext passwords is not security, it's the illusion of
security. There's very little authentication, no message integrity
checking, no disclosure protection, and no non-repudiation of origin.

That "only thing" is very hard to do, and won't scale.

Here I'll agree in principle; we should invent as little new stuff as
possible. But there are other constraints; we should be consistent
with existing tendencies in the protocol, keep the protocol
request-response, and have something that will scale adequately.
(Something that can be used in the U.S. would also be nice.)
