Certainly not optimized but also I think the very definition of a stall. Ground school was ages ago for me but I do recall a bit of it. I thought the laminar flow on the top was vital for lift even a slight ripple was bad. A flat wing top and bottom would not create lift or poor lift. Well at least for aircraft with flaps and aelerons that need consistent airflow to maintain control. The difference in the bottom flat part of an aircraft wing compared to the curved top part is what creates the difference in velocity; faster bottom, slower top which creating lift. But again maybe not necessary if you are not in an aircraft that needs to be controlled. The ramblings of a former private pilot student, but an eternal fan of physics.
