This goes back to 2010:

        /*
         * XXXEACH: This call to configure_view_acl() is redundant.  We
         * are leaving it as it is because we are making a minimal change
         * for a patch release.  In the future this should be changed to
         * dns_acl_attach(view->queryacl, &view->cacheacl).
         */

Please review.
