  Afaik FLAC this days uses an ogg container, which is where
  the metadata goes, so support should be as good as for Ogg
  Vorbis.

  In practical terms, I have a huge collection of FLAC, and
  never had trouble with metadata, sounds like a bug in
  whatever player you were using.

The Ogg container is optional, and I can't say I've seen it used much, if ever - I gather its main use was for streaming. FLAC has its own metadata as part of the spec: http://flac.sourceforge.net/format.html#metadata_block
