Gets a ``ObjectiveBankList`` corresponding to the given objective bank genus ``Type`` which does not include objective banks of types derived from the specified ``Type``.

        In plenary mode, the returned list contains all known objective
        banks or an error results. Otherwise, the returned list may
        contain only those objective banks that are accessible through
        this session.
