There has obviously been an undercurrent for a while that some folks 
would like the spec to just define the syntax of DNT in the TPE spec and 
to be completely silent as to what it means.  I remain opposed to that 
approach for the reasons previously stated and reiterated here.

Of course this fractures DNT.  If I go to a publisher, and 10 third 
parties respond ackNAI, 10 respond ackIAB, 10 respond ackW3C, 10 respond 
ackUS, and 10 respond ackFU, that means those parties are doing 
potentially very different things in response to the DNT:1 header which 
completely frustrates the purpose of standardization.  Users cannot 
reasonably be expected to keep track of the varying regulatory and 
self-regulatory models and evaluate them.  I'm not sure how user agents 
will respond to this panoply of response headers, but it is conceivable 
that they will be configurable to only allow content that ack in certain 
ways, or that add-ons will be available to do that for them.  I think 
the balkanization of DNT would push us down the TPL/ad block road, which 
from my point of view is a bad result --- I would prefer to see the 
ecosystem define DNT:1 in a consistent way, and respond to those headers 
by either serving non-tracking ads and content, or requesting the user 
to grant an exception (or turn off DNT entirely if the prompts get too 
annoying).

Again, the value add here is the standardization of what the header 
means.  The header is out there today --- any company can publicly state 
that they follow NAI's opt out rules in response to the header if they 
want to.  If the end result of this process is that the meaning of the 
header is outsourced to whoever wants to define it, then we have not 
solved the problem this group was tasked to address.
