I really couldn't say why it was done that way. Maybe to reduce spam or something, although I can't see that as being the case. Channel refreshes are sent every 30 seconds, regardless of whether they NEED to be or not. Anyone who administers a hub ( like me ) will be able to see this in the hub's logs. Obviously there's no valid reason for it to continuously send these out if the information isn't changing. Only thing it does is spam the network with needless packets.
