Well, you said that this "is the poster child for exploiting browser
state."  For it to be a serious threat that warrants consideration, you
must assume that most users read certificate data (regardless of whether
the browser is actually throwing a warning).  If we can assume that most
users do *not* read this information, then there's a plethora of much
easier/likelier attacks.

That is, it's a waste of time worrying about how a burglar might pick
your fancy new lock when you regularly leave all the windows open.
