Pardon the silly question, but apart from the increased weight and complexity, why aren’t jet engines designed to be feathered as a props are? I’d imagine the N1 blades at the front create a lot of drag just windmilling, so why isn’t there a way to reduce drag? Or are jets typically so powerful that engine out climb performance is still healthy?

On an equally silly note, do jets and turboprops have counter-rotating engines? I ask because I remember being taught about the descending blade producing more thrust in PPL school. Since turboprop and turbojet blades are airfoils, how do those planes escape the need to correct for it the same way a piston pilot has to?
