surely you agree that this puts the feds in a much tougher spot though?

I think we should try to get from a 4 to 5, even if we can't get all the way to 10 right away. We shouldn't just punt on the problem because it's not possible to have an immediately perfect solution. 4 to 5 might mean using keys that only the customer has access to. 7 through 10 might all be political, sure, but let's keep moving.
