What's the point of including a connection ID (and stateless reset token) in the `preferred_address` transport parameter if that CID isn't tied to the preferred address in any way? At that point might as well remove that CID entirely and rely on NEW_CONNECTION_ID frames. My understanding was that the reason for there being a CID in the `preferred_address` TP was specifically to make that CID special. Would it make sense to just say that this CID MUST NOT be used when sending to the handshake server IP?
