MQTT AddOn: Birth and Will status

Hi, Would be nice to have the option to enable: topic: "hass/status" payload: "online" topic: "hass/status" payload: "offline" The Birth and Will status. The Birth status work when you modify core.config-entities but the will is a problem. A automation will not work always, because HA is offline earlier then MQTT can receive the publish

Hope my explanation is correct.
