What level of support would it be? Read status and report device Healthiness based on it? Allow changing the heartbeat interval via configmap option?

Read status and report device Healthiness based on it?

Yes, each scan checks for -1 in status and sets pluginapi Health accordingly.

Allow changing the heartbeat interval via configmap option?

I think not, at least for starters. The interval is fixed on 4xxx and if configuration is needed, a custom initcontainer could do it.
