It's built on the correct assumptions. You just don't understand all
possibilities why a service process can crash/exist, even if it's a
most perfect software ever written. Shit happens, and supervision will
attempt to restart the service for any reason it exits/killed. Including
human error, of course. What you've never killed the wrong process by
mistake? What if you set an rlimit, and the service reaches it, the
kernel will then kill the service. With supervision it will be
restarted, without it, the service will be down. Simple as that.
Programs have bugs, including memory leaks.
