Yes, that's true. However, we could be very lax about the "nano-second
precise" bit of it. No one has to know if you have a nanosecond precise
time source or not. If you don't, just implement a message ID counter
and dump that in the nanosecond field. See this email for a further
explanation:

If we take this approach, we don't need a nonce spec. If we take the
Message ID approach, we need a nonce spec. Trying to cut down on the
amount of work that needs to be done and code implemented for this
stuff. I also realize that this is being nitpicky, and could live w/ the
nonce-approach if that's where consensus is.
