Mike, 

good point. But if they collect that identifier in a first party 
context, they can't share it with the third party. Thus the third party 
can not use that identifier to select the appropriate profile data to 
deliver to the first party. Because otherwise, the third party would get 
the information that user cookie xyz1234 is now visiting example.com. 

So if they share uniqueID with third parties or offline data providers 
under data append strategies, that would not be conformant under the 
current specification IMHO. 

I still think they are saying the same thing. It may be that some still 
believed that the current text would allow append. I don't think it does 
as it rules out necessary preparation steps for data append.
