So if you're responsible for a big fleet of things and you have costs to handle every failure, it makes sense to have supervision to reduce these costs. Most users with a few machines never observed any failure ever, independent of the operating system and (server) software. If this would be the argument to decide if supervision is necessary, nobody would need it. And yes, the BSD world tries to be conservative compared to Linux and yes, OpenBSD tends to be the most conservative BSDs related to changes. But I think that isn't the most important thing for decision. I.e. your super stable BSD doesn't help against DoS attacks (read as overload), unstable hardware, misconfiguration of services, packet loss, ...
