Because mentioning it works. As somebody who uses many different languages professionally, I immediately assume projects written in Rust are more reliable, more robust, and more efficient. My own projects are higher quality when I can use Rust to implement them, despite having much more experience with most of my other languages.
As a user experimenting with tools, ones written in Rust have justified these prejudices. They simply tend to be better.
It's an effective advertisement. I'm a little confused why there's always someone who brings it up. It's not like programming language makes absolutely no difference. If it's written in C or C++ and it's relatively young, I'll expect it to be unstable and to have a clunky and unpleasant interface. If it's in Go, I'll expect much better in stability, but with a funky CLI. If it's Python, I know it uses argparse, so at least the CLI will be consistent. If it's Rust, I expect it to be fast, to have very few or no panics, to have no memory issues, to have zero null pointer problems, and to use clap for a very consistent, predictable, and good looking CLI.
The language has built a good reputation; I'm shocked that commenters on HN have somehow avoided picking up on that and are perpetually surprised that it has a real audience.
