Weeeeell.. Maybe…

As we have seen, when simply rolling keys getting the timing correct is "tricky", and folk often manage to screw things up. 
I suspect that, in a non-insignificant number of cases, the adversary would cause temporary validation failures for a number of folk, which may provide a signal that something has gone South… :-P

I don't think the execution is relevant when it was obviously a bad idea in the first place.
This is like putting rabid weasels in your pants, and later expressing regret at having chosen those particular rabid weasels and that pair of pants.
