Also it does not speak to the fact that the verifier could have access to a graph cache, rather than just a representation cache (http cache). And in your case you would have access to a graph cache so then you would end up already with a graph, and therefore there is no need to parse the graph again.

For an https://... WebID this would be done using the [HTTP-TLS] protocol. The dereferencing of the URI MAY use any representation caching mechanism it can to speed up the process. The returned representation is then transformed into an RDF graph [RDF-MT] as specified in Processing the WebID Profile . This graph may be cached.

Ok, those changes are now in.

Ok. For the RESTfulness of the spec I have asked people on REST discuss to see if they can give us feedback.
