Refreshing of paramters need Queued Messages?

[mike_k]

How come that everybody assumes that queued messages needs to actually be queued, in some of my devices that support queued messages I only queue the message type. Hence it need only a few bits to store each queued message.

A good responder should send back changes through queued messages, and a good controller should make sure it have necessary data available, regardless of how they do it.
