 When an endpoint issues a connection ID, it MUST accept packets that carry this
 connection ID for the duration of the connection or until its peer invalidates
 the connection ID via a RETIRE_CONNECTION_ID frame
 ({{frame-retire-connection-id}}).
 
+Endpoints store received connection IDs for future use.  An endpoint that
+receives excessive connection IDs MAY discard those it cannot store.  An
+endpoint that issues connection IDs cannot expect its peer to store and use all
+issued connection IDs.

Belated question: when you discard them, it seems you should not send a RETIRE_CONNECTION_ID frame, otherwise you may just get more?
