Well, if I _really_ wanted to assume stupidity or malice on the part of the server author -- and often it's useful for clients to do exactly that -- I'd point out that the latter is only a 'SHOULD' and the former although 'MUST' is predicated on the server actually _observing_ a change, not on the mere fact that there _is_ a change. But in practice I suppose I can't see anyone claiming "But we didn't check for the change hence we didn't observe it" as an excuse, so it does come very close to being the 'MUST' which I was after, and which I'd missed.
