It's not about being additive or subtractive. It's about DoS'ing the 
consumers.

With subscription forwarding it gets even worse. The "get all" 
subscription will travel all the way from the consumer to the ultimate 
publisher and DoS all the devices on that path and thus cause disruption 
of service for all other subscribers connected to those devices.
