Let's look at the practical effect here, assuming people were to actually follow such a recommendation. The only audio codecs that are implemented in browsers but not available for WebRTC are the ones used for HTML5. According to http://html5test.com/ these codecs are Vorbis, MP3, AAC, and uncompressed PCM. These are the codecs that would be recommended under such text. None of them is really ideal for interactive audio, none of them is implemented in old phones AFAIK, but all of them would require time and effort to add to a browser's RTP stack. I really don't see the point here. Jean-Marc
