I believe that it’s not literally hardwired in the sense that powering up the camera also powers up the camera LED, and instead this relies on logic in the hopefully un-flashable camera+LED firmware. Someone correct me if I’m wrong.
You need some logic to enforce things like a minimum LED duration that keeps the LED on for a couple seconds even if the camera is only used to capture one brief frame.
I have a script that takes periodic screenshots of my face for fun and I can confirm the LED stays on even if the camera only captures one quick frame.
