Redundant `to_string`?

I was surprised that there does not seem to be a lint to catch the following. Is it possible that it exists and I am somehow not triggering it?
```rust
use camino::Utf8PathBuf;

fn main() {
    let path = Utf8PathBuf::from("src/main.rs");
    println!("{}", path.to_string()); // to_string is unnecessary since Utf8PathBuf implements Display
    println!("{}", path);
}
```
