I really think we shouldn't disallow connection migration when the server uses zero-length CIDs. As stated above, linkability can happen for a variety a reasons, and we should leave it up to the client to decide whether it wants its bytes to go through or not. Perhaps an editorial paragraph stating this in the migration section or security considerations would do the job.
