After using Fedora for a number of years I have found the strict Dspace model
hard work.
Although there are plenty of issues with using triple stores and RDF based
systems for representing structural relationships IMHO the benefits are worth
it.

I agree that I never liked the concept of bundle very much, mostly because of
the minor annoyance of yet another natural join when writing SQL queries. OTOH,
I know people who depend on the concept with their extensions of DSpace. So it
would be highly desirable to preserve backward compatibility at least on the
API level.
But I like the idea of items directly containing bitstreams and their relations
being described in another way.
The possibilities of storing RDF in a SQL database also seem to be well
explored:
