pathlib.Path supports deletion of both files (Path.unlink()) and directories (Path.rmdir()).

Unfortunately, Path.rmdir() does not allow deletion of non-empty directories which means users must use shutil.rmtree() when deleting such paths.

Since pathlib.Path already supports file and (empty) directory deletion, adding Path.rmtree(missing_ok=False) would support both the utility and the completeness of pathlib.
