Not much point unless we also deprecate all of the other auth methods
that require cleartext password transmission, which from a quick
scan include PAM, BSD, LDAP, and RADIUS.  Seems unlikely to fly.

In any case, I don't think this is about password security per se.
It's more about deprecating a method that might look like it's
secure but isn't.  In the case of the cleartext-password methods,
it's obvious that you'd better use SSL or GSS encryption if you
want your password hidden from network tapping.

I don't recall how in-your-face we are about that point, but
certainly the docs need to be up front about it, and probably
make the point explicitly with respect to the four methods
listed above.
