Other service supervisors implement systemd's readiness notification protocol. For example, s6 implements it with the s6-notify-fd-from-socket[1] program. libsystemd::daemon::notify already checks for NOTIFY_SOCKET being set, which should be sufficient to tell if systemd-style readiness notification is wanted.
