We plan on landing the following changes to the Attribution Reporting API focused on: * reducing transmission loss by supporting reduced aggregate report delays * additional API configurability by supporting an event-level reporting epsilon field * improved extensibility of the API by failing registrations when encountering reserved keys
Based on a combination of ecosystem feedback and to improve transmission loss, API configurability, and ergonomics.
