That's what is funny to me too -- they're basically phasing out all furnaces and hot water heaters that aren't direct vent (bringing in combustion air from outside) because it's so problematic to have gas-burning appliances in your home. Yet we just burn gas stoves -- some of which are massive without question...

If you were to use all of the burners on this stove on their highest setting, it would consume more BTUs than a 6-ton Furnace! And it just vents into your indoor air: (https://www.homedepot.com/p/Cosmo-36-in-6-0-cu-ft-Commercial...)
