In some cases you want sorta aerodynamic vehicles even if they are space only, as you then can do aerocapture and aerobreaking, possibly reducing quite a bit the delta-v needed for a flight. Also high thrust engines if you can get them can make use of the Oberhausen effect & some maneuvers, like specific orbit captures or crewed radiation belt transits need them as well. Still no problem to build that thing in space if you can pull it off. :)
