For that matter, any maneuver that requires a straight line approach requires good rudder control. You cannot enter, say a good Half Reverse Cuban Eight without entering it straight and level. The level is aileron, the straight is rudder. Then, pulling straight back on the elevator stick to the required 45 degree angle, then straight, at that angle, followed by the inverted flight (again elevator followed by rudder to keep it ( straight being the nose pointing in the right direction) then the pull under to finish up the maneuver, requires some rudder to keep the nose pointed in the right direction.

For pattern folks, they are graded, scored, on how the maneuver looks, if it is straight, and if it has the right components. Minor corrections are allowed because control is what it is all about, and doing the maneuver as close to perfect is an absolute. Even in wind, which is always there, so it takes rudder control to do this and mastering it is a goal.
