I would then recommend to go with the DocumentWithUsefulStuff option and
keeping DOM Core's Document interface (and Element interface) useful for
all DOM implementations.

Yes, but also documents with elements from multiple namespaces, like an
SVG document inside a XHTML document, are a concern here. The individual
ExampleDocument interfaces are difficult to access in that scenario, and
you have to adapt scripts if you change the structure of the document. A
different approach like the one you propose would have to provide an
answer to these problems.
