It wouldn't be superior for you, but if an FAI, (or just a person trying to live by the principles of Fun Theory) to, is at some point required to simultaneously optimize an environment for both you, and someone who likes pleasant surprises, that would be an effective way to satisfy the other person's desire for pleasant surprises while simultaneously satisfying your desire to never be surprised in certain ways. It would be a good way to fulfill that Principle of Fun without harming any of the people whom it doesn't apply to.
