Maybe I'm naive, but what I see is a presumably RDF-less container listing+GET/PUT/DELETE, which seems like yet another attempt at encapsulating the "hard bit".
If one day the spec has access grant requests and ESS is spec-compliant, then other apps would be able to talk directly to the wallet's data.
On the other hand, I consider this particular access grant API rather complex, and would hope that it gets encapsulated a bit more if it gets to the spec.
