The metric "my naive Rust" vs "my carefully implemented C" might be OK, once you figure out a consistent way to check code passes as "my naive Rust" or "my carefully implemented C".
Until then it's just an anecdote.
Might there be programmers whose "naive Rust" performs a lot worse than their "carefully implemented C"?
Might that be unsurprising to them and uninteresting as a blog post?
