If the output device - that is the replication source - goes away (hot plug) we need to clear the `replicationSource` field in the other output device. This is straight forward with a single connect but question is if afterwards the replicate event should be send to clients with null string (and a flag indicating that this source removal was due to a hotplug and was not set explicitly) or if they should just conclude this from the other output device going away. A similar case is the replication source being switched off while staying connected. Here the output device does not go away, but the wl_output normally should. Still it makes sense to not replicate an output which is switched off. So remove the replication source in the compositor and then signaled to the clients?
