Sure, they left the committee years ago. I am not trying to claim any sort of direct causality, but it sure seems like this is a case where Google's presence on the committee might have prevented shipping boondoggles like this. Modules is another case where I think Google's feedback might have been able to steer the ship in a better direction.
