From what I can find, seems opus only supports audio. ogg also has a video format (ogv), odd it is suggested ogg was superseded by opus. Maybe I am missing something ?
Ogg is the container, Vorbis is the audio codec, and colloquially people just called Vorbis-encoded audio "ogg" because of the ogg container.
Vorbis was hit-or-miss. In some cases it did better on same or lower bitrate than MP3 encoded by LAME, in some cases worse. It also suffered an entirely new category of "chirpy/tweety" artefacts similar to what MP3 exhibits at very low bitrates, but with Vorbis they showed up even at nominal bitrates during certain complex spectral patterns. I was a vocal proponent of Vorbis back when it surfaced, but soon changed stance when realizing how unreliable it was quality-wise.

I would bet that the primary reason wasn't the container format, which nobody really cares about and most users wouldn't have been aware of, but rather the fact that the file extension was '.ogg'.

I was going to suggest you missed vorbis ogg. So I went looking for a link, I found out this:
I never heard of Opus, so some links:
https://en.wikipedia.org/wiki/Vorbis
https://en.wikipedia.org/wiki/Opus_(audio_format)

Ogg is a container format. It contains audio and video tracks: https://www.xiph.org/ogg/
It's like Matroska: https://www.matroska.org/what_is_matroska.html
Or MP4: https://en.wikipedia.org/wiki/MP4_file_format

Kinda happens everywhere. "I'll send it to you as an MP4" versus "I'll send it to you as an h264+aac"
That is what I meant.
