Everybody always adds this little thing. Who gives AF about what Rowling wants or likes. It's not up to her. I'm sure when Disney has construction going on, Walt wouldn't like a large crane shooting out of the background of the castle, but it has to happen. Progress needs to go on because you can't just make a crane invisible. It's up to universal to make it a seamless as possible, but they can't just magically make a ride appear without having construction done.
