Any plans to expand the list of standard field names in comment header?

[Zapeth]

I'm not sure if this is the correct place to put this, but I was wondering if there are plans to extend the list of standard field names in the comment header?

More specifically I'm looking for a way to add lyrics metadata to my music files, and formats/players that make use of id3 tags seem to implement this via the UNSYNCEDLYRICS tag (at least WMP supports this).

However the current Vorbis specification doesn't list an equivalent in the comment header. Of course I could set a custom comment and make up my own format, but I'm hoping that a more future-proof solution could be established, especially since other codecs like flac and opus apparently use the same comment header format.

edit: I looked more into how some audio players tend to implement lyrics functionality, and it seems most have settled on using a LYRICS comment tag for unsynced lyrics in Vorbis header data -> https://wiki.hydrogenaudio.org/index.php?title=Tag_Mapping#Miscellaneous

It would be nice if this (or other commonly used tags) could be added to the specification at some point, but otherwise I guess this can be closed again since I've found what I was looking for.
