Yes, this would work.
My service (written Python) uses the journald API.
Disadvantage: My script can't be run under a different environment (without journald)
I let my service write json to stdout and a wrapper collects these lines and the wrapper uses the journald API.
Disadvantage: Systemd is monitoring the wrapper, not the real service. Signal handling for stopping and restarting
is not direct from systemd to service.
The perfect solution is not found yet.
