If instead users can pick and choose, then you know either "i have no exception and should ask if i want one" / "i have a site-wide exception" / "i have no clue, some part of me has an exception but whether that's sufficient for me or not I don't know so now I have to poll, and for privacy maybe I don't even get to poll for specific things so who knows". The latter necessitates polling as you can't reasonably list all the third parties that have exceptions in the request headers.

Whether or not the JavaScript API allows tracking exception requests with a list of origins, users may have configured their browsers to send DNT:0 to some origins and DNT:1 to others.

Whether or not the JavaScript API allows tracking exception requests with a list of origins, we can design a capability to make it easy for a publisher to know if they have a site-wide exception (that is, that all their third parties will receive DNT:0). We've heard suggestions of a JavaScript list or a DNT:2 or DNT:10 header. I think we have postponed ISSUE-111 for that issue, although I think we don't need to postpone it, since it's independent of the question we're discussing now.

Thanks,
