> Small devices, like the original Arduino, may have very limited resource, like 16k of RAM, or less.  For such devices, limiting the storage used by MQTT is very important.  
> They may not even be able to process a message of 30k, for instance, at all.  If it were sent at QoS 1 or 2, it has to be read in before subsequent messages are received.  
> At the moment, it is a server admin task, or application design task, to make sure that messages bigger than a device can handle are not sent to it.
