It is hard to imagine an RDF server that would NOT. Without having such a mechanism provided by the RDF Server, it is almost impossible for users to craft queries that accomplish the same thing using normal means. But collection membership seems like such an obvious test that users will do, I would assume an RDF Server should already have provided optimized indexes for this purpose (how horrible to do a recursive query every time someone does a membership test), so exposing the query through some API or property is an obvious thing to do IMO.
