 If a local urlpath is provided, i.e. a "file://" or "local://" URI, the returned
 instance type will be a `FilePath` instance. This class is a subclass of `UPath`
 that provides file access via `LocalFileSystem` from `fsspec`. You can use it to
 ensure that all your local file access is done through `fsspec` as well.
 
+All local UPath types are `os.PathLike`, but only the `PosixUPath` and
