It is strange to see this method returns a scoped_ptr whereas the two preceding
methods return a plain pointer.

Why isn't this method an abstract method (= 0)?

Should be addressed by the name change.
John mentioned, the new convention for content interfaces is to provide an empty
implementation instead of pure virtual. The other ones are from before that
convention.
