> @@ -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.

I think this discussion is a good reason to not have the enforcement (i.e. close the connection if peer exceeds the maximum).

As @ekr has pointed out in https://github.com/quicwg/base-drafts/issues/1994#issuecomment-441305154, the `max_connection_ids` can be a purely advisory value without defining any error conditions.
