Standards are standards. If you don't follow them or update them without going through the proper channels then you are creating something that doesn't confrom anymore. You can say to yourself that a pound is 17 ounces and do all your own math that way, then go to sell something that is supposed to be a strict pound and you will be wrong. AAC is a much better compression scheme than MP3. It's good enough that I can deal with 192 kbps AAC over 320 MP3.
