There is no way of getting the values of properties for a non default aspect unless the call with String IRI, String Aspect remains, unless we were either to re-introduce aspect as an Interface or unless we were to introduce an ANY_PROPERTY value.

That is already the case. There is no call that allows the specification of an IRI.
