Thanks to Kacey for keeping so hard on this question! Drawing he posted and his related comments are enlightening!

IMHO, I agree those scoops make sense only to give some sort of supercharging, providing a room where air pressure is higher, thanks to recover of dynamic energy.

Indeed, about twenty years later, that became a common practice, increasing rated altitude on its own of about 1500 m.

Nice finding!
