If you're going to have a full IDE where you can write and compile code that Apple has never seen, it makes sense that developers would be able to download and run unsigned binaries inside the terminal for development purposes. Attempting to arbitrarily differentiate between unreviewed code that you're writing and running versus unreviewed code someone else wrote that you're running would be a strange line to draw in the sand. If they somehow decide to provide Xcode but don't provide a terminal at all, that would obviously be very limiting.
