Do you mean something like having an ogg packet which contains an ogg page for
some sub-stream or something like that? Of course, the spec doesn't disallow
this, since it doesn't say anything about the contents of the packets, but
it
certainly doesn't encourage it, and I see no reason why you would do so.
Or maybe you mean something else, and just failed to express your meaning.

We're not going to change the bitstream format so that your implementation
can
be slightly more convenient. The format is fixed (though future versions may
differ, of course).
