Even without any LLM usage after the rewrite, there might be a change in license as seen with similar projects, which supports your argument.
From the article:
> The company points to projects such as uutils coreutils and sudo-rs as examples of Rust implementations that have earned a place in the distribution.
uutils is licensed under MIT, instead of GPL like the original coreutils, and thus it would be easier to grab.
The article's claim that the Rust implementations earned their place in the distributions is also not true, it was more that they were forced into Ubuntu despite bugs and memory unsafety in the Rust implementations.
The general trend is interesting. C is an ancient language, and it is also minimalistic. And while Rust has lots of features with lots of problems, like its borrow checker that among other problems drives code towards deadlocks and TOCTOU bugs https://fasterthanli.me/articles/a-rust-match-made-in-hell , some of Rust's other features, like tagged unions and pattern matching, are by themselves attractive to many developers.
