It was not considered to be removed, and I’m doubtful it ever will be. Legal and safety would win this. There would be a lot of discussion in even trying to move it so it flows better within the narration and story. Guests try to stand up, they try to jump seats, they try to move car to car, they try to take pictures, you name it. They need to stay in their seat during rotation and descent or there is a real danger to both themselves and the guests around/below them. Even something falling from a pocket accidentally is a hazard during descent. And there’s a danger they could get caught during rotation. The danger isn’t they will jump, it’s that they will be standing or doing something dangerous when the car rotates and starts the descent. Guests have a bad habit of trying to do dumb things in the top of the dome. The announcement serves as a verbal cue in advance.
