I guess, but not a big deal to standardize it, since:

Correct.  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.
