The author notes that the resulting Rust port is not very "rusty", but I wonder if this could also be solved through further application of the same principle. Something like telling the AI to minimize the use of unsafe etc., while enforcing that the result should compile and produce identical outputs to the original.

It seems feasible, but I haven't thought enough it. One challenge is that as you Rustify the code, it's harder to keep the 1-1 mapping with C interfaces. Sometimes to make it more Rust-y, you might want an internal function or structure to change. You then lose your low-level fuzz tests.

That said, you could have the LLM write equivalence tests, and you'd still have the top-level fuzz tests for validation.

So I wouldn't say it's impossible, just a bit harder to mechanize directly.
