Snap! OK, I'm convinced. Suspend :)
Given the DigiNotar experience, this is a dead cert.
Reason being, DigiNotar has established a liability pattern, and the CA
mentioned above has figured out that it might apply to them.
Under normal corporate governance escalation procedures, "might" becomes
"are you willing to bet your job?" Risk modelling out the window :)

Somebody on one of these lists made the point that the attacker wasn't
acting like what was expected in the designed threat model.
It is not a new observation that the original threat modelling had flaws
you could drive a truck through :) To add to that, the original
security requirement was to protect Credit cards. Only. Which have a
known value range, a loss model, an insurance model, institutions
already at arms to protect Robbie Relier.
So, when people started using SSL for other purposes (email, banking,
but not porn) ... what happens?
Well, the value changed (up or down?) ... and the insurance disappeared.
Perhaps this is just another one of those aphorism moments?
