Re: Collaboration with Social Web Incubator CG (re: alsoKnownAs)

From an LD a.k.a. RDF point of view, adding that extra does not really make any difference: logically the JSON-LD represents the same triples. The @set container comes to the fore when the JSON-LD file is compacted, transformed, etc, and it gives a somewhat more predictable shape for those transformed versions. Whether that is of any importance for DID applications I would not know. However, having the two context files in sync probably makes sense.
