Does/has Rockbox support(ed) .opus or ogg-opus?

[thinad]

Just a few quick questions.  Does rockbox support opus or was support for opus ever implemented in Rockbox itself? I wanted to use opus as my player has very limited space but I saw it wasn't included on the manuals. I saw a few posts online and it seems like opus was supported at some point.
For example, https://forums.rockbox.org/index.php?topic=43118.0 and https://old.reddit.com/r/IpodClassic/comments/m1hcr6/to_rockbox_or_not_to_rockbox/
I checked the manuals of both players mentioned and a few more. The manual clearly specifies Ogg/Vorbis. I would check it myself but my player's broken. I'm trying to figure out how to convert mp3s and id3 to Opus and Vorbis comments but it'd be pointless if it isn't supported. Thanks in advance.
I don't believe either of the players mentioned above have hardware support for .opus.
I'm guessing the decoder isn't stable or efficient enough.

So, let me get this straight...  despite Rockbox's manual saying that Opus is supported [1], you're asking if rockbox supports Opus?

TBF there is nothing on that page that says 'opus' there also is no requirement the file be named .opus which is where OPs confusion lies I think

pretty sure it can be .ogg and then the codec is then specified as opus

but yes we support opus (not sure about the naming though)
the format might matter so before you go converting your whole lib check a few first and get your settings nailed down

Everything's clear.

Thanks. 
Ogg's just a container for codecs. Why is Vorbis singled out in the manuals? Since Ogg's a container the only reasonable explanation would be that Vorbis is the only supported codec in ogg. Just my interpretation.
