There was not consensus about what those precautions are against, either 1) collecting data that could be correlated across first parties, or 2) commingling data across first parties.  David's draft text proposes the former rule (which de facto encapsulates the latter rule), and I am in support.
I do not recall consensus on this. Wasn't there dissent regarding the 
feasibility of such precautions? My view is that legal requirements in 
this technical standard are not workable.

No, I don't think we had consensus that a "user expectations" test 
should be used. A user expectations standard is absolutely unworkable 
for companies trying to implement. From my conversations with others in 
industry, the one thing almost everyone says they want out of DNT is 
clarity. The ambiguity of a user expectations test would, in my view, be 
a disaster.
