strongly disagree.  the problem is that when you try to negotiate the most
secure settings possible, you often create a way for the negotiation to be
dumbed down by an attacker to the least secure setting possible.

Not if you store the settings that you negotiated the first time
(ssh-style "leap of faith") and allow the user to check the stored
settings.
