I'm much more sympathetic to the aggregate feed problem of multiple IDs. People advocating this type of thing seem to think the default action should be grouping, so they want to use the same ID. I think that's a bad idea, and there are plenty of other ways to indicate the fundamental sameness of entries. For example, NewsML URNs have a NewsItemID and a RevisionID, which would allow smart aggregators to group the entries without violating Atom's constraint.
Then you have two ways of indicating fundamental sameness of entries, one for when the same entry appears multiple times in a feed, and one for everything else.
Back to basics then. Does anyone remember why having the same id in a feed is a bad idea?
