Arguably we could detect them and complain. It's possible this could detect misconfigurations or other mistakes, but: - as far as I can tell common webservers like apache do not have any mechanism to pass arguments to a CGI at all, so this isn't a mistake one could even make - it's possible that some obscure webserver might pass arguments, and we'd break that case. I have no idea if such a webserver exists; the CGI standard says only "The script is invoked in a system-defined manner". So probably it would not hurt to detect them, but it also is unlikely to help anyone. Let's just mark them as unused, which retains the current behavior but silences -Wunused-parameter.
