Misleading/incorrect statement in Opus codec registration

The Opus codec registration states the following:

The conclusion I draw from this is that when description is set, the bitstream is in the 'ogg' format. However, this is not necessarily the case. description may still be provided even if the format is 'opus', and the 'ogg' format may not even be supported even if description is being set.

Here's a repro link: https://jsfiddle.net/7d1fLmbz/4/
I'm on Chrome Version 131.0.6778.86 on Windows 11.

I think what the registration is meaning to say is that each user agent is free to set description if they want, it's just when they set it it needs to be an Identification Header. It's very useful that it does this and I make use of this description field myself. However, the presence of description cannot be used to conclude whether the format is 'opus' or 'ogg'.

Start with the Opus codec registration text referenced in the issue and compare its wording with the linked JSFiddle reproduction. Revise the statement so that providing description is not presented as evidence of an Ogg or Opus format, then verify that the clarification matches the WebCodecs API behavior.
