The CGI mechanism let the web server call a separate local binary passing parameters of the request as envars/stdin in a specified manner. The "cgi-bin" was just a server side directory where those CGI binaries lived.
If I understand the GP's point, they like the idea of dropping a singular binary in a directory on a server and then it's magically available as an endpoint off the cgi-bin/ path.
