Every place has different design standards and idiosyncrasies. Since the 1980s most of the new apartments in Israel are rather large 4 and 5 room apartments. Only recently there has been a change to build more 2 and 3 room apartments because of sky rocketing real estate prices. Walk in closets is simply not a design feature that Israelis are used to or want it. I think most would rather have a smaller closet and not waste half a room on such thing.
