This new method allows checking if a path is root without cloning or constructing anything. Currently, I believe you have to do either: * `path.as_str().is_empty()` which is less semantically obvious and exposes the implementation * `path == path.root()` which is a bit more expensive because cloning an `Arc` requires atomic operations. Previously, you could also do: * `path.parent().is_none()` which had similar issues to `path == path.root()`
