John,
No one working group member owns the "purpose of DNT" - that's the point of the working group effort to arrive at a consensus end-point that collectively develops "the purpose". Artificially constraining the group to not be able to think outside of the box and be flexible to real-world situations doesn't help advance our collective goal (at least as I understand it).

In addition the proposal to have a separate opt-out mechanism undercuts the purpose of DNT.

Justin,
Here is my friendly amendment to Lee Tien's change proposal for Audience Measurement.
Simply remove from the TPC Audience Measurement as a permitted use.
Justification.
It is straightforward to arrange that agreed panel members can have their user-agents override any DNT:1 general preference on requests to audience measurement servers using a web-wide UGE or with an OOBC signal. Insufficient evidence has been submitted showing why standard statistical methods extrapolating panel observations would not work, and why it would be necessary to use persistent unique identifiers on every request irrespective of someone's preference not to be tracked.
