Or are jets typically so powerful that engine out climb performance is still healthy?
It's probably already been answered in one of the replies. But if you could "feather" the fan section, there's still A LOT of metal behind that that would cause drag. The rotors/stators, combustion chamber, and every accessory attached to the core of the engine creating a profile contributing to the drag.
