"If you manage to find a vulnerability in this system, I don't think I even mind, "

Taking a quick photo doesn't illuminate the LED for long enough for a human to reliably notice.

"because you've also broken physics "

Or merely recognized the role of the human element. A shame, Apple was once good at this.

What does it look like if an app takes a series of photos once a second while shutting on and off the camera in between?
What if only the camera is allowed to shut itself down and never responds to such requests if they happen weithin the first one second after it has been powered on
That requires software. Software can be reprogrammed.
Newer Macs will also require the light to come on for a lot least a few seconds when the camera activates.
That sounds like the led is controlled by logic, instead of being in the power loop.
You could connect the led to a capacitor, which would be charged when camera is connected to power, and would discharge powering the led for a few more seconds after power is disconnected.

But yeah, I wouldn’t trust a led, because I can’t reverse engineer the circuit that’s in my particular device.

Who enforces that requirement?
