[temp-dir] Why not depend on `remove_dir_all` crate on Windows?
The README for
temp-dir notes that the crate might fail to remove the directory on Windows, and suggests
remove_dir_all crate for that. Is there a reason why it's not used in
Drop implementation? It will only be a dependency on Windows, and it can even be put behind a Cargo feature so people can accept the risk of leaving directories around.
