"Turned off" should be considered a dangerous state you can't leave the system in - in fact, if due to some failure the system ends up turned off, it should continuously alarm or trip the electrical supply.
Just like it's really hard to turn off the drivers airbag in a car.
The approval logic was, people will:
- always be very careful cooking, and never ever let the heat get too high
- people will learn about teflon, and keep watch
- people care
Meanwhile, stories abound of people's birds dying from toxic gas (they are more susceptible, and die first).
Note that if a bird dies, and you don't, that doesn't mean you were not injured. Or your family.
If you're giving anything to a consumer, assume they know nothing, that they cannot follow directions, won't care even if they understand, etc, etc.
Because that's how it is.
This is validated, proven, over and over and over again.
I love the idea of airtight, but think it is like lead in pipes. If we build like this, kids ... with their developing brains and bodies, will pay the price.
And 40 years later, we'll be astonished at the absurdity of it all, the lost potential, wasted lives. Just like lead pipes, paint, etc.

Grab a pan and wipe a tissue around the inside a few times... See the dirt that comes off... That's probably carbon and teflon deposits.

The same offgassed chemical is now under the teflon, between pan and teflon, as well as in any cracks, or porous areas of the teflon, more likely now, as teflon has changed its chemical struture.
It's where the gas came from, yes?
So, now you have a pan more likely to crack and chip, with deadly chemicals waiting.
The logic you are employing, is similar to the logic which got a deadly substance, teflon, approved.
OK under some circumstances, but not thinking of the entire picture.
The price? Your health.
The health of all in your house, breathing toxic gas, and eating toxins, for which the young are more susceptible to.
This is classic "what's wrong with the world" stuff. For an extremely mild convenience, use a deadly solution at a whim. Teflon.
People would rather have their food covered in toxic stuff, than use a little oil. Or buy an iron pan, and season it correctly.
