As far as I know (which is very little), you're right - disabling the ability to produce light doesn't disable the camera as long as the software thinks the light is on. There are likely hardware-only approaches but they may be prohibitively expensive for a feature no customer wants to pay for. That's the big difference between designing a light for the owner's protection (who probably won't disable the light and will notice if it breaks) versus a light for the protection of others (who might not know to look for a light in the first place, especially once Glass evolves to look like regular glasses). There's a laptop accessory market for physically blocking camera switches with state determined at glance. Wearable cameras may need to adopt a similar mechanical approach for today's social expectations, but putting switches on your face is somewhat at odds with designing away from the Glasshole Borg look.
