I think that people who've tried to work around the "default" / "unanamed" graph (note, singular) in SPARQL can agree that's it's at best unfortunate, and at worst a giant pain in the arse.

If you have exactly one graph, then there's no issue (you never need to refer to it), but as soon as you have >1 it starts to bite you.

All this thinking about trying to save bytes in the representation I find very concerning - it seems to be assuming that this data is being typed by someone - if your system has people typing in significant quantities of RDF then something is pretty odd, IMHO. We should be aiming for clarity, and unambiguity IMHO, and I don't see how anonymous graphs help.
