Request for expiry_after option in MQTT HVAC integration

Some of the MQTT integrations (e.g. sensor) have the option to set up a expiry time using the expiry_after parameter. This shows whether the publisher for whatever reason stopped sending updates.
The climate module doesn’t have this feature. I just created an MQTT publisher for Daikin AC units and it would be great if I could see if for whatever reason my app stopped working.
Thank you
