It's great, you can have it launch multiple processes on the same port using SO_REUSEPORT. Normally it'd be a bit of a pain to health check multiple processes running on the same port without some other machinery since it is possible to get into a state where all but one process is hung. Systemd watchdog will provide your service with a socket and expect updates on a regular interval or else it will consider your service dead. This socket is also very handy for service startup, to have your process just notify systemd it is ready rather than having to poll to see if your process is listening yet.
