I may be misinformed but the article says
We’ve verified that every AST produced by the Rust parser is identical to the C++ one, and all bytecode generated by the Rust compiler is identical to the C++ compiler’s output.
which I took to mean that the new code behaves 100% identically to the old code, like a byte-perfect decompilation. If that’s not the case and it’s just the same in their suite of tests then I’d agree with you.
