Mike,

The discussion on that part largely revolved around what sites an option
has when it receives a request that, for whatever reason, it believes
doesn't meet the bar. We've said from the beginning that no one is forcing
sites to implement DNT (or browsers for that matter). We are coming up with
a specification for what DNT means, we have no power to force anyone to use
the specification. The question came up something along the lines of "So,
what happens if I get a request from an IE10 user with DNT:1, what options
do I as a site have?".

There's some people in the working group who felt that if you as a site
support DNT, then you must support it when you see DNT:1 and you have no
business second-guessing the UI decisions made by the browser or the level
of compliance of the browser. You see DNT:1, you do your DNT:1 thing,
whatever that means.

There's other people in the working group, myself included, who feel that
since you are under no obligation to honor DNT in the first place (it is
voluntary and nothing is binding until you tell the user "Yes, I am
honoring your DNT request") that you already have an option to reject a
DNT:1 request (for instance, by sending no DNT response headers). The
question in my mind is whether we should provide websites with a mechanism
to provide more information as to why they are rejecting your request, e.g.
"You're using a user agent that sets a DNT setting by default and thus I
have no idea if this is actually your preference or merely another large
corporation's preference being presented on your behalf." Given that DNT is
optional and the only regulatory hooks are what you sign up for and say
you're going to do, someone suggested what Aleecia paraphrased in her
email, "we comply with the W3C DNT specification except we ignore
non-compliant user agents.". E.g. the site determining what amount of DNT
compliance it wishes to claim and under what circumstances. Perhaps we go
beyond there, perhaps we don't, who knows, but that was where the
discussion started to go.
