The argument is that one can treat g-snaps as immutable g-boxes (or g-boxes as mutable g-snaps, if you prefer  it's the same thing) without losing anything.

You can assign IRIs to anything in RDF, including any concept you can possibly think of. You can assign IRIs to cars and people in RDF, even though RDF doesn't know anything about cars and people. Same for g-snaps.

The question is whether the RDF data model should contain built-in constructs for certain things. Experience shows that built-in support for *some* of the g-* things would be a win. The argument is that support for g-boxes is sufficient, because that allows handling of g-snaps as immutable g-boxes.

Best,
