If the program exits with a special status to indicate non-restartable failure, you could, in principle, recognize that in the process manager and handle it differently, by not restarting. Is there any way to do this in systemd, or in any other process manager?

Yes, systemd has "RestartPreventExitStatus" to configure a list of exit codes which prevent the automatic restart.

Was there not a recent blog/article that mused about the likelihood of systemd spawning all manner of special case entries?

And now i ponder likening systemd with CISC...
