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.

It's probably done to keep it in a low powered state and reduce the initialization delay. Maybe also to prevent the Windows USB plugging sound from playing upon turning the camera on, as it would seem weird to the user ("I don't have any USB devices plugged in...")

Likely UX over security and privacy.
