I can imagine that situation in theory, but what real-world usecase leads you to use named graph, but where the metadata applied to the whole document?

It seems like a corner case.

Database dumps are one possibility (but then you'd often have both dataset-level and graph-level metadata), but those are more commonly in nquads formant, from what I've seen.

Strongly agreed, though I don't think many people share this concern.
