I support this. I wish we could choose how many doors we wanted our rooms to have. My house is fully enclosed meaning there are no doors to go outside, but it's not the ideal setup I wanted. I just didn't like the look of doors leading out to nothingness. Ideally I think it would be cool if the Questing Hall for example, could just have one-door.
but i would also add that for rooms with multiple entrance/exits i would have the OPTION to remove a door if it does not lead to a room with a wall that would normal let you through
