I don’t think this is the only purpose. I can see a case mainly for archival. Another use case might be RecentChanges newsfeeds for wikis, where there generally is a concept of minor and major edits that are nonetheless all considered to have significance, just of different levels. I can certainly see these use cases to an extension element and I don’t think it would hurt much to do so. I wonder, though, if it would hurt anything to introduce an OPTIONAL atom:modified element for those cases where the publisher wants it, and that it only means something when provided? In particular, publishers would not be required to provide it and would certainly not be required to change it for “every change to an entry.” It would be nice for use cases such as wikis if clients could be relied upon to understand such an element when present.
