All you are really doing is figuring out a way to come into the ball with the clubface closed, square or open. You are not controlling that through the impact interval. Whether you have a full roll, half roll, or no roll feel again you are just figuring out a way to get to the ball with the face in a certain condition.
That being said I think hinge action is important to give people a balanced motion. As a player you can achieve certain shots with with the different feels of hinge actions. Even though you may not be actually changing the face through impact interval , the feels can help you get the clubface into different conditions coming into the ball.
