 An endpoint enters a closing period after initiating an immediate close
 ({{immediate-close}}).  While closing, an endpoint MUST NOT send packets unless
 they contain a CONNECTION_CLOSE frame (see {{immediate-close}} for details).  An
 endpoint retains only enough information to generate a packet containing a
 CONNECTION_CLOSE frame and to identify packets as belonging to the connection.
-The connection ID and QUIC version is sufficient information to identify packets
-for a closing connection; an endpoint can discard all other connection state.
-An endpoint MAY retain packet protection keys for incoming packets to allow it
-to read and process a CONNECTION_CLOSE frame.
+The source and the destination connection ID and the QUIC version are sufficient

Just talking about "connection ID" is insufficient though, since I need to remember at least the connection ID I'm receiving packets at (which I would have called my source), and one connection ID I'm sending packets to (which I would have called my destination).
In addition, depending on how frequently the peer switches to new connection IDs, I maybe should also remember the outstanding connection IDs I've issued to my peer.
