Many advertisers engage in media transactions outside of real-time bidding (RTB), such as direct upfront deals with publishers.

Presently, advertising servers and Dynamic Creative Optimization (DCO) providers can utilize two types of data: 1) information from publishers and 2) insights about advertiser audiences to make decisions regarding creative optimization.

Considering the importance of safeguarding privacy, can the Protected Audience APIs be extended to support non-RTB media transactions and maintain critical use cases such as ad serving and DCO?
