Re: why I don't like default graphs in the DATASET proposal

I realize that a statement that I made:

could be argued against by the way SPARQL defines a dataset:

I do not read "which does not have a name" as *forbidding* the default
graph to be *also* a named graph, because the SPARQL rec also says:

And indeed, I see more value in having a named "version" of the default
graph in the dataset than in not having it.
