I interpret that standard saying that this also applies utilities that do not take any flags. And to be on the safe side I think it is a good idea to support “--” for two reasons: (1) existing scripts may require it, and (2) if POSIX adds a flag to the utility in the future we must support “--” now, otherwise compatibility will be broken.
