Exactly, you can use PID to turn a small craft or a large ship, or to heat a tiny copper vessel or an enormous iron one. Delayed effect and tuning time to setpoint and overshoot are, like, well within its territory.

PID doesn't care how long it takes to achieve stability but sometimes you do.

In a lot of cases the time to settle is so short that it doesn't matter but sometimes it does. When you operate datacenter you might not want to wait for hours for PID to spin up the right amount of servers.
