Definitely low effort.

Cars, using the gas oven for extended periods with no ventilation, or fires with the flu closed....

What is the enablement? Who made the recommendation to run cars in confined spaces or ovens without ventilation?

Who's going to pay for them? What was stopping people from putting one or two in the house? Legislation may affect more builds, but how are you going to police existing construction?

I don't think you'll get a straight answer on this one.
