Hi,
The point that Alan raises has been mentioned before on the mqtt wiki
pages that cover specification clarification and improvement:

> Hi,
> A lot of MQTT client libraries offer the feature of generating random
> client ids rather than having to supply one. This is good.
> I recently had over 10,000 client connections made to
> test.mosquitto.org using a random client id, but also having set clean
> session to false, which meant that when they disconnected their
> information was stored on the server but there was basically no chance
> they could reconnect.
> It would be nice to have a comment in the spec suggesting that
> implementations may offer to generate random client ids but that they
> must refuse to do so if clean session is set to false.
> Cheers,
> Roger
