And for things where retpoline isn't needed it's unambiguously wrong (wrong in that runtime is slower than it should be for no gain). What are you not getting about that? They made a decision that when it's wrong it's still safe, but it's still going to be wrong for a non-trivial amount of users.

Yes, I know, that's why I said what I said. Which was correct and supported by both the spec and your statement just now...?
We're not talking about hypothetical future WASM, we're talking about WASM as it exists today and what problems it can/can't effectively handle.
