The easy answer is that rosters (and the IRoster interface) predates
ISubscriptionService by quite a bit.  The latter was added primarily to
support REST APIs for member searchers.

The concept of a roster as a query is pretty fundamental, and the idea was
also that rosters should be composable.  I'm not keen on changing these
interfaces.
