[B&A] Parallelization Support for Bidding and Auction Services

Will the Bidding and Auction Services support parallelization with the "contextual" ad request, as discussed in WICG/turtledove#385?

We support the unified flow / unified ad request.

Seller's ad server may call B&A while the contextual auction is running. You may read more about the flow here- https://github.com/privacysandbox/fledge-docs/blob/main/bidding_auction_services_api.md#flow

Parallelizing Contextual / RTB and B&A auctions would be a further latency optimization.

We do plan to work with different SSPs to incorporate further parallelization of contextual / RTB auction and Bidding and Auction services, so that B&A can be called earlier. However, this needs to happen without impacting traffic shaping in seller's ad server.

We will keep you posted. Thanks.
