This is unnecessary, it's not advertising on Rust. The README directly explains why they describe `eza` as modern. It makes no mention of Rust or memory safety.
Personally, I use eza because of `--tree` and `--git`.
You really shouldn't. You're adding to the stereotype that Rust developers are insufferable and not to be collaborated with. Scaring away good developers from your projects is a bad thing, not a good thing.
