I also fully support this Ambisonics work, and am very happy with the progress progress thusfar.
There'd been interest in Ambisonics in Vorbis for a long time (more than 15 years at this point), but there hadn't been a group that was qualified in practical Ambisonics, motivated to do the work, and had the time resources available for a long-term investment. It's natural this interest would move forward to Opus, and I'm glad to see it finally sink root.
