My concern here is twofold. First, this is halfway through a document which is entirely focused on interacting with graph stores, and this is essentially the first time default graphs are discussed. Second, I didn't read this as "explicit text". Certainly not in the way Update deals with defining a graph store ("a Graph Store contains one (unnamed) slot holding a default graph and zero or more named slots holdingnamed graphs").

Yes. I was expecting/hoping for a an actual definition of what the graphstore is. The terminology section provides what looks like a definition, but it isn't all that specific, and doesn't mention default graphs at all. If the GSP is going to rely on the definition in Update, I think it should have some text to that affect, not just a citation link next to the (different) definition.
