This is absolutely the correct and standardized way to do mechanical rewrites: you do a rewrite that maps directly to the original source so you can rely on the original correctness guarantees and bug-for-bug compatibility and log issues, and then you go into the next phase where you begin to use idiomatic constructs.
This is the same in COBOL-to-Java ports that have been done in banking and insurance for the past 20 years.

it isn't, because those guys didn't think a naive 1-1 machine translation would give them the benefits of Java, which somehow the people involved in this rust rewriting seem to think they've already gained despite the virtually identical code.
If the whole point genuinely would have been to do a purely mechanical translation they could and should have written a transpiler, which would have had significantly higher correctness guarantees than this given that it'd be deterministic, but of course that would have defeated the PR purpose of this whole thing, which just looks like a marketing for Anthropic frankly
