Hi Jack, Rachel, Alan, Peter, Brooks, Chris, David, Max, Tim, Mike, Ari, Vivek and Nadine,
Thank you for your comments (last June) on the TPE Last Call Working Draft. The Tracking Protection Working Group has discussed each of the issues and proposed resolutions. This email in particular describes discussion and proposed resolution regarding validation of DNT signals.
Editor Roy Fielding has provided a detailed response to different comments related to this issue in email; I have provided the link below. I would briefly summarize the resolution as:
* testing and other means can help to validate signals but specification cannot provide additional proof

Thanks,
Nick Doty, W3C (for the Tracking Protection Working Group)
