I’m quite sure they could, but mostly just because they could simply walk into your house and tamper with the hardware. You don’t need a fancy zero day when you’re the government.
Turn up with a bunch of fire engines, and a gas company van. Knock on your door, and 3-4 neighbors on each side, for good measure. Tell there's been a report of a gas leak, and you need everyone to leave their houses/apartments immediately for the inspection. 15-20 mins later - you can come back in, all's safe. Thank you for your cooperation.
