If you look at

,----

|  if (init_is_systemd) {
|    do some systemd stuff;
|  }
|  else {
|    carry on as before;
|  }

`----

you'll note that the

if (init_is_systemd) {
    do some systemd stuff;
} else {
    /* syslog(LOG_EMERG, "ESYADMINDEPRECATED!!!"); */
}

is nothing but "systemd support code added to some package".
