The claims they make seem sensible - everyone's known about the
possibility of such downgrade attacks since forever - which is why
clients generally won't allow both PLAIN and non-TLS at the same time.
What clients really need to do is cert pinning and mech pinning to
prevent these exploits in all but the first-login case.
