It seems to me that all sites must respect DNT when the message is sent.  The interesting question is what the compliance responsibilities will be.  I'll grant that there are different levels of response depending on then user's relationship with and expectations of the site.  As I understand the issue, "First" party and "Third" party are conventions that are fairly well understood.  (I don't know how we got there, though. Logically, I'd think of the user as the first party, the site whose URL is entered in the browser as the second party, and other content served to the Second Party site as coming from Third Party sites, but that's not the convention.)

I think talking about "explicit" and "implicit" consent is the same as discussing talking about first party and third party, so I think we ought to stay with conventional terminology -- First Party responsibilities and Third Party responsibilities.

It's essential to stress, however, that ALL sites have responsibilities when they receive a DNT message.  In  the compliance standard we'll need to spell out those standards.  It could well be the case that  good actors with best practices will wish go beyond their minimum responsibilities when they encounter and honor the DNT request.

As Aleecia's research has expressed, users do generally understand the difference and I believe our work should reflect that.  If we move to "explicit vs. implied" it seems like we're right back in the same place and are simply shifting terminology but the substance of the discussion is the same - which is "where is the DNT signal expected to be respected?".
