I don't think new builds in this country (unless they're large houses and it's for show) have had chimneys for close to fifty years.

Bathrooms needing an openable window for ventilation lasted longer than chimneys here and I guess those were gone by like the turn of the century because fans†?

I feel like kitchens even if not burning stuff should have proper extraction fans. So I think there likely will be more balanced view with proper ventilation and air quality.
