Hi all!

We are currently exploring migration from origin enrollment to site enrollment for the Aggregation Service (current form using origin here) for the following reasons:

• Consistency with the client API enrollment that uses site
• Ease of onboarding for adtechs, so they don't have to enroll each origin individually

As a follow up to this proposal, we would like to support multiple origins in a batch of aggregatable reports. Do adtechs have a preference or blocking concern with either specifying a list of origins or the site in the createJob request?
