Andrew Banks commented on MQTT-217:
-----------------------------------
MQTT253 (add subscription ids) tried to address this but was abandoned. Other ways to address this, might be:
- Require that a server that sends multiple messages should mark all but the first message as repeat a message.
- A server should announce on CONNACK that it is going to send multiple responses when needed.
- The server should add a unique identifier to a publish message so that the client can eliminate the repeat messages
if it needs to.
> Deliver implementation guidance around overlapping subscriptions
