Tiru, Even if we assume that ACL-specific stats can be communicated via the signal channel (which we don't have an agreement on it so far), this is not specific to the filter-control spec but the same reasoning would apply for all ACLs instructed by the DOTS client (not only those that are adjusted during attack times).
