I'm not sure that the answer to this question will require any
change to the document but wanted to check... 

I wondered about the privacy properties of these (and related)
WebRTC identifiers, esp. if they are being handled at various
different layers. Is there work somewhere in the WebRTC space
that's analysing that? For example, one concern might be that
msid-appdata could end up with some kind of privacy sensitive
value, but there's no guidance here about that and as the
examples use UUIDs it's not clear to me those represent nor what
typical values will be used. (Note: I'm not saying that I
believe this is a problem, I'm just checking if it's been
considered.)

I hope that there's no reason why these can't be very ephemeral
values that don't identify (or help re-identification of) people
or their preferences, locations etc., and I'd imagine there's
little reason to e.g. log them. If that's the case wouldn't it
be useful to add such guidance (somewhere, maybe not here)
to help developers to do the right thing?
