I thought the whole point of these camera LEDs was to have them wired to/through the power to the camera, so they are always on when the camera is getting power, no matter what.

Having the LED control exposed through the firmware completely defeats this.

The idea has been around for quite some time. But it is always dropped.

My guess is that, assuming the most basic and absolute physicial design, the light would flash for silly things like booting, upgrading firmware, checking health or stuff like that.

Flashing is easily fixed with a capacitor and also not a bad thing if it turns off when it loses power immediately. The only explanation that makes sense to me is it being separately controlled is a feature not a bug.
