I agree they are quite different but they converge on some things, e.g., 
the default graph has the same meaning in both approaches.

Id doesn't *require*, it just *allows*. So it makes possible for an 
implementation to define extensions that constrain the interpretations 
to denote the same thing, if required.

Getting true graph naming in my framework would be possible by adding 
just one additional condition on interpretation, but I deliberately 
avoided putting this constrain, to accomodate for the use cases when 
graph IRI denote primary topic, for instance.
