Opus is still improving, v1.1 to v1.2 then onto v1.3 (current in FFMpeg) saw huge reductions in compute for encoding, and the minimum bitrate for stereo wideband fall year after year.

The limiting factor for Opus's penetration has been compute, FEC is still rarely supported on VOIP deskphones due to this, ditto for handling multiple Opus calls at once.
