> @@ -3981,6 +3979,12 @@ A client MUST NOT include an original connection ID, a stateless reset token, or
 a preferred address.  A server MUST treat receipt of any of these transport
 parameters as a connection error of type TRANSPORT_PARAMETER_ERROR.
+max_connection_ids (0x000e):
+: The maximum number of connection IDs that the peer is willing to store.
+  This value includes only connection IDs sent in NEW_CONNECTION_ID frames.

@kazuho: I think that's fair, and I'm ok with not closing the connection if a peer violates my max_connection_id. We need to be clear that an endpoint that drops a NEW_CID because it has no space MUST NOT send a RETIRE_CID. This is an easy bug, so it's worth noting.
