Good points, I would offer up it is again an AND not an OR. Sometimes the metadata is all you need and other times you may need the whole thing. An application that your parser can't decode or understand could be an example. The plus in all of this is that the tool capabilities are converging. As a consumer, to help with complexity, I would seek out tool-sets that use or benefit from a common platform based approach focused on interoperability
