It's unlikely to be used that way except in a small minority of cases.
Jerry is absolutely correct that the practical result will be that most
users of OpenID will become more vulnerable to compromise of a single
password. This will only increase the value of several kinds of attack
(phishing, exploiting client security flaws, XSS, CSRF). I bet that
attackers are rubbing their hands in anticipation.
