I agree in general with this reasoning, but come up with a different end point.

If systems are storing RDF datasets, and exchanging them (even if not 
globally), and have a very limited (or even null) theory of the interaction 
between the default graph and the named graphs, then we should be very careful 
in breaking this form of interaction.  This would be another rationale for not 
having information bleed from the default graph into the named graphs.

Any bold decisions then have to have convincing rationale.   There has to be 
something very useful that comes from the boldness and there can't be much 
broken that isn't totally unredeemable.
