Real-world unfair tests could matter, though it’s not clear if there are any. However, hypothetical unfair tests aren’t very informative about what is a good decision theory, because it’s trivial to cook one up that favours one theory and disfavours another. I think the hope was to invent a decision theory that does well on all fair tests; the example above seems to show that may not be possible.
