I am a bit concerned about reopening dataset semantics discussions here, but an argument for including some of this would simply be to specify the behavior of a store when loading a dataset serialisation (e.g. a TriG file) which imho is very desirable. Or at least an unambiguous way for such stores to explain what approach they're taking when loading a dataset. I think that would be covered by the union and merge operations. Perhaps there could be room for that in the dataset semantics note?

Best,
Yves
