The header itself must be there, even in empty form, but the contents are 
totally optional.  Here's another implication I meant to get into the original 
proposal and forgot:

The comment field does not contain any data vital to decoding of the audio
stream; all decoders may feel free to entirely ignore the comment header.  The
comment header must, however, be present even if the vendor string and comment
list are both empty.

Sure :-)

Ah, by 'vendor string', I intended this to be a text comment to identify the
encoding software (eg, our libvorbis, a forked/tuned libvorbis, a totally third
party encoder), not the organization producing the bitstream.
