Could you map out the scenario as you see it happening? It sounds like you are mixing two issues.

1.     Are you stating that a 1st party cannot use 3rd party data in real-time, that is not impacted by DNT, for personalization?

2.    Are you stating that during an offline state that a 1st party cannot perform data append? There is DNT signal at that point.

3rd data append companies bundle huge data sets that include public information, but also proprietary information.  Offline is also integrated with online as well.   I don't think (in the US) there is serious consent to the current state of data append.  This is not out of scope for a robust DNT spec.

Again, under the current framework of our standard, first parties will not be able to share data with each other about DNT:1 users.  And, third parties will not be able to collect any data about DNT:1 users.  You are proposing to restrict first parties from acquiring data that is publicly available, collected with consent or offline data.  This is out of scope for DNT.

First parties now engage in data append with many, many data partners for targeting.  It's a common practice and should not be permitted when a user signals DNT.
