Is this statement true? What about NAT rebinds?

If this statement is strictly followed, no one ever migrates because they're waiting for the other side to do so. (At which the other side has violated a MUST, and you really ought to kill the connection to that naughty endpoint!)
For both client and server migration, this actually points in the same direction, so let's accept the non-generic here: "A server MUST NOT send non-probing packets to a client address until it receives a non-probing packet from that address."

This paragraph: > A server MUST NOT send non-probing frames to a client's address until the server > receives a non-probing packet from that address. Is true only with the restriction of migration to client addresses. It complicates the server migration story if we ever want to do that (as we already have with the proposal for preferred addresses).

Remove unnecessary text from #1253
Define probing/non-probing packet and frames.
