The chrome flue pipe is required to vent the products of combustion from the oven, but an actual exhaust hood is optional (although the occasional building inspector may disagree). In this case we eschewed it for just the reason you mention: it fit the homeowners' vision, and they are enough windows for general ventilation as needed.
