What about saving private tmp and var/tmp paths to service struct when service is started and then systemd-tmpfiles can obtain all currently used paths and skip them (but not their content)? I don't think that simply skip /tmp/systemd-privat-XXX would be a good idea because these dirs would be never deleted even if the service is already dead.
