+## Authenticating Connection IDs {#cid-auth}
+The choice each endpoint makes about connection IDs during the handshake is
+authenticated by including all values in transport parameters; see
+{{transport-parameters}}. This ensures that all connection IDs are authenticated
+by the cryptographic handshake.
+Each endpoint includes the value of the Source Connection ID field from Initial
+packets it sends in the handshake_connection_id transport parameter; see

I think it's called `handshake_connection_id` because it is the connection ID used during the handshake, I think it's a reasonable name
