Understanding question about lyrics in flac files. UNSYNCEDLYRICS flac tag

The term configurable vorbis comments in flac is used there. What exactly does this mean? The COMMENT tag?
Is the UNSYNCEDLYRICS supported? Because myMPD don't show anything under lyrics tab in song info.

I have flac files here from bandcamp where ffprobe outputs the following:

Input #0, flac, from 'GUNSHIP - UNICORN - 01 Monster In Paradise (Feat. Milkie Way, Dave Lombardo, Tyler Bates).flac':

You can configure the vorbis comment names from which myMPD reads synced and unsynced lyrics. Enable it in settings -> features and you can configure the comment names. Defaults is LYRICS for unsynced lyrics.

Thank you ! i replace LYRICS with UNSYNCEDLYRICS and the lyrics from flac vorbis tag show up but one thing i notice is that the lyrics of every track begin with "=" what does not seem normal if i look at ffprobe output.
