I don't understand the reference to the 'D' status;  the last sentence should read, in my opinion

 If an origin server subsequently determines that it does not have prior consent to track a user, the origin server MUST then respect the user's DNT:1 signal (and signal so).

In addition, and missing here

When the 'P' status value is signaled, the 'edit' member of the well-known resource must give a URL in which the user can (possibly with some latency) find their actual status.

(in discussion on the call, that page might say 'please wait while we retrieve your information';  I think we set an outer limit of how log, but I cannot recall what it was)

Unlike C, the origin server does not know, in real-time, whether it has received prior consent for tracking this user, user agent, or device. Since this status value does not itself indicate whether consent has been received for a specific user, an origin server that sends a P tracking status value must provide an edit member in the corresponding tracking status representation that links to a resource for obtaining consent status."
> Non-Normative: The P tracking status value is specifically meant to address audience survey systems for which determining consent at the time of a request is either impractical, due to legacy systems not being able to keep up with Web traffic, or potentially "gamed" by first party sites if they can determine which of their users have consented. The data cannot be used for the sake of personalization. If consent can be determined at the time of a request, the C tracking status should be used. If an origin server subsequently determines that it does not have prior consent to track a user, the origin server may not then disregard the user's DNT:1 signal; rejections of DNT:1 signals must be made in real-time, using the tracking status value of D defined in 5.2.8.
