   For one thing, to avoid writing the following code:

================== code snippet ============
        GUPnPServiceIntrospection *introspection;

        introspection =
                gupnp_service_info_get_introspection (
                                GUPNP_SERVICE_INFO (proxy),
                                NULL);

        if (introspection) {
                const GList *variable_node;

                variable_node =
                        gupnp_service_introspection_list_state_variables (
                                        introspection);

                for (; variable_node; variable_node = variable_node->next) {
                        GUPnPServiceStateVariableInfo *variable;

                        variable = (GUPnPServiceStateVariableInfo *)
                                   variable_node->data;

                        gupnp_service_proxy_add_notify (
                                        proxy,
                                        variable->name,
                                        variable->type,
                                        on_state_variable_changed,
                                        NULL);
                }

                g_object_unref (introspection);
        }
==============================================

   But i now that i think about it, this is needed by generic clients
only and they would be using and depending on introspection anyway.
