But why can't one have "the best of both worlds" without having to go
to separate pages for each photo?

Depends what you mean by "covered". I'd say the RDFa examples of this
"cover" it better in the sense that they don't impose an arbitrary
restriction that the license only applies to a single object (or I
suppose group of objects).

This isn't really my area, but I could imagine an organization (in
particular) wanting to include machine-readable license links (a la
CC).
