It might not be a feature, but it is a selling point. It conveys that it was written relatively recently, is more likely to support modern features in the shell, runs reasonably fast and is reasonably portable.

If it was written in JS or python I'd already start worrying about what package manager to install it with in which environment, installing it globally is an anti pattern but symlinking it to .local/bin might complicate it.

So IMHO, the language something is written in is not just an implementation detail, it informs me in how well it will perform.

It's a prompt. Writing anything for that purpose is code gardening, but hey it's in rust so I'm supposed to be excited?

That, in essence is the problem "X in rust" normally means "I've written something of low value IN RUST. Gimmee upvotes". Come back when the project is interesting regardless of the language.
