I don't understand why we would say that a 1st party most likely will not be subject to the DNT signal.  If we continue to use the 1st party/ 3rd party distinction, it will likely (almost certainly) have different and probably fewer obligations than a third party. It should still be subject to the signal.

As a user I want the 1st party site to know that I have DNT configured.  As a 1st party site operator I want to know a visitor has configured DNT and is sending me the signal.  There will be some "musts", ie not sharing data from a DNT configured user with 3rd parties, but if I am a responsible site operator I may chose to go further in honoring the DNT request.  For instance I might chose to not even include the visitor in my analytics. I need to know if  DNT is configured and the way this happens is by being subject to the DNT signal.

The obligations are different, but its important that we think of all sites being subject to the DNT signal, once it is configured in the browser.

This will leave room for sharing with Agents/Service Providers/Vendors to the 1st party -- as well as sharing aggregate and anonymous data with "others" (general reporting, for example).
