You can still get access to the QR feature/Bing Vision, you just have to look under Lenses. I was also bummed about this change, but used it infrequently enough that I don't mind it being located under Lenses. If you check the Store, you can even pick up an app called QR for Cortana that can be pinned as a shortcut to get quick access to the Lenses menu.
