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 isn't clear to me that webcam firmware ever powers down a typical camera module. See below for data about how the Sony IMX708 sensor is an I2C device with start and stop streaming commands.
