Dear Michael,

As already discussed in meetings, and pushed by Jonasz in this pull request #194 I would like to reiterate the need to have reporting on both the trusted server signals and user bidding signals.

This reporting may be differential private, but it is extremely important to have reporting on signals that are used in the bidding if we want to be able to optimize our campaigns, leading to higher ROAS for marketer and spend on publishers.

Without this, we won't be able to use fledge as intended during the origin trials and the testing steps, meaning that we will have misleading results to share, as either we will use models not trained on fledge (not available once 3rd party cookies are removed) or used a degraded version of fledge without the signals that can be used to have better performance.

Could you please therefore confirm that you intend to incorporate reporting on all signals in fledge, by a secure reporting mechanism, as soon as possible in the process?

Many thanks!
