The question of browser support, and its details, is relevant.  For 
example, meetecho is best supported by Chrome and less by Firefox (lacks 
device switching).  That might prevent some people from using meetecho 
instead of installing Chrome.  Which translates directly into preventing 
them from participating to IETF.

For opus - firefox does support opus, it seems.

Mp3 might be a format that, despite its longevity, might not be 
supported by some browsers because of the licensing scheme.

Other than browsers, there also the players: there are many players of 
live streams out there, which are not web browsers.  Many of these 
players dont support mp3.
