You may disagree but perhaps you can tell me where it says so in the standard? The wording is very clear and I don't see where you get that interpretation. The requirement is that "--" is discarded so that portable invocations work. That is what is says, nothing more. The second sentence explaining this makes it perfectly clear that the intention is NOT to require implementations to implement option parsing when no options exist but rather to make it possible to have portable invocations.
