Raphael Cohen commented on MQTT-262:
------------------------------------

If you have clients configured with duplicate client ids, then there's not much we can do until we add an explicit server-initiated DISCONNECT. Adding a server-generated client id will also help. Regardless, I'd still advocate this behaviour. Having clients with duplicate ids is a serious misconfiguration, and isn't a scenario it's reasonable to expect a broker to detect under normal operation. It is possible, but with scaled out brokers, it's fiendishly difficult.

> If a server disconnects a connection because a second client has connected with the same client id, should the first connections' will message be sent? I would argue it should, because this scenario is intended to reflect 'stuck' and 'hung' clients.
