While I don't necessarily disagree with you as far as abstracting the source of data goes, but it's never "prohibited", it just considered bad practice. Personally I've never understood this "thou shalt protect the superglobals" attitude. They're arrays, nothing more, use them in whatever way you want to. They're not sacred, endangered or likely to be overcome with the urge to kill you if you modify them. If your code changes its behaviour depending upon whether the data you're dealing with has come from within or without your code I think you have bigger style issues to address. All hail the superglobals!
