That's useful, but it's not as reassuring as a hardware switch where you can see it work.

(For video, anyway. I don't see any similar solution for audio.)

Two reasons why switch is better:

1. If it does happen to light up, what would you do, turn off your computer? That's shitty.

2. What if your AFK and aren't looking at the light?

A switch plus a notification (as opposed to modal prompt) if you try to get into video/audio calls but forget to flip it back. Just to remind you that you’re trying to enable video/mic but have the hardware switched off.

Arguably better to be aware of the breach than prevent one sensor from leaking too.
