I think this might actually be the most sensible and important new
thing anyone has actually said on the list on this topic for a long
time now :)

It gives me that warm fuzzy sense of hope that this is not just a
difficult compromise we've become resigned to, but actually something
with some real technical merits all of its own.  It hadn't really
crossed my mind in this discussion that there'd be some implementers
who really would just ignore the whole negotiation thing to hardcode
only their preferred codec -- which is kind of like saying I'd not
thought about what colour my hair is, I don't have to think for very
long to know what the real world answer to that would be.

Thanks for bringing this up for those of us who didn't make it to
the meeting and have been too busy to watch the recording yet!
