Is there ever a case you'd want to use &String::new() for something expecting &str?

In a previous PR to clippy, an suggestion from the maintainers (@flip1995) came up to create a lint detecting passing an owned string to something expecting where "" would be accepted. I want to follow up on this and open an issue (and perhaps a PR) to implement this, but first I want to make sure I'm not missing anything.

There are ways to enforce it, for example declaring the variable const or static, or using the nightly feature inline_const: https://github.com/rust-lang/rust/issues/76001 which would allow you to write let s = const { String::new() };, ensuring that everything from inside the const block is evaluated at compile time.
