Hello, A few hours ago, Christian Huitema pointed out to me that the "M" letter in the 20th Implementation Draft [1] only covers usage of server CIDs by the client. (I thought that it meant "migration to server's preferred address is successful.")
We should have a dedicated letter for this. I propose:
F: Success if server specifies a preferred address in its
transport parameters and the client migrates to it.
