That only seems cosmetically similar to me. If cruise control would usually do the same thing but occasionally try to take a curve for me, I would consider it unreliable. Even if it always got the curve attempts it made correct, it is unreliable if its actions are not essentially a mechanical response.

Right, this is the difference between most car functions and then something like FSD. Reliability. Cruise Control always works the exact same, where the car will break/accelerate exactly as much as it needs to, to maintain the speed it is set to go. Same thing with ABS, where the brakes will be perfectly pulsated when heavy braking. Or differentials. Or pretty much any car system.

FSD is a little too wild west. I also lump ACC and LKAS in here, too. Phantom brake and bad directional input exist for those way too often.

But it’s a function you can choose not to use. My Model Y doesn’t even have FSD, I didn’t buy it. I could buy and use it, but I don’t. It doesn’t concern me that it exists, the Model Y has been an awesome car. If I did buy and use it, its limitations are widely known and I’d expect to supervise it if I used it.
