From your answer, it looks like you don’t understand the point that I’ve raised. Let me rephrase it: How are we supposed to differ the Javascript files (legitimate action) without cheating the pagespeed tools (debatable action) using your plugin? If the answer is “you can’t”, then there is a legitimate concern you are encouraging cheating the pagespeeds and the first thing you should do is to fix that ASAP if you wanna keep your integrity intact.
