Just in case it should come up on Wednesday:
I've just realised I mightn't have been particularly clear about
my reasons for the suggestion: it's for future proofing.  At
the moment there are problems if you try to add CMML or
the mythical metadata format to a Vorbis I/Ogg stream.
AFAIK Skeleton should now work okay with libvorbisfile
players, but for future introduction of new codec types*
this would be useful.  This was also what I was thinking
about when I suggested may drop unrecognised streams.

* Especially metadata, subtitles and other codecs that don't
  need to be decoded for the other stream contents to be useful.

Have I mooted providing a Vorbis I stripper tool* before
in this context?  It's trivial and might be helpful for
backward compatibility purposes.

*Or simple library function.  Potentially something I'd
 have time to finish.
