I am not being clear, oh dear.

I am saying that there are two scenarios already covered by our specs, for a user using DNT:

a) they do NOT opt-in to this site that is sometimes 1st, sometimes 3rd; under those circumstances, the widget shown in 3rd party status is the same as the one shown to unknown people
b) they DO opt-in, possibly in-band, possibly out-of-band; then the 3rd can show personalized content.

Given the existence of an opt-in, to achieve case (b), we don't need to bend case (a) to behave the same as (b).  Case (a) can and should stay in the 
    "treat me as someone about whom you know nothing and remember nothing"
camp.  IMHO. I think.

In the absence of that cookie, the 3rd party receiving a DNT signal has no business applying 'heuristics' (fingerprints etc.) to guess who I am.
