Not saying without kitchens so much as smaller kitchens. When you look at new home construction in the past 10 years, they have MASSIVE kitchens. A lot of them are bigger than my first apartment.
Accessory dwelling units ("ADUs") are becoming somewhat common because it lets people throw down a tiny (sometimes pre-fab) cheap housing unit that they can rent out. Many of these don't have real kitchens (no stove, etc.).
