I would not be surprised given that Tor was specifically created to anonymize the traffic of US spies. It was released to the public to give plausible deniability to the spies. A new protocol that ONLY spies used would be obvious to track down, no matter how much encryption it had. But if everyone is using it for different purposes then you have to actually have to break the encryption to know if someone's using Tor to check in with the CIA or if they're just so paranoid that they insist on surfing Wikipedia with it.
