I don't read it like that at all. Rust is mentioned only once. Nevertheless I do care if a tool I am considering to use is written in JavaScript, Rust or some esoteric language. It means a lot, not only for "safety" which is not important to you that much, but also for maintainability, community, and the future of the project. Of course, what triggers you probably is mentioning Rust in the title of the post. Still hard to imagine being so annoyed by it–if authors thinks it's important or it will grab attention, why not use it...
