Currently, my filter only evaluates signatures that are relevant to From
alignment, and stops after the first success.   For that decision process,
all that I need returned (and stored) is a Pass/Fail result; I don't need
the details of the algorithm evaluated.  Any additional information
collection is for the benefit of someone else, not the needs of my own
organization.

The burden of data collection is proportionate  to the amount of data
collected.  DMARC reporting is a courtesy service from the data collector
to the domain owner.  Each effort to increase the precision of the data may
reduce the number of domains willing to provide that information.

I suggest that we need report consumers in this group to discuss how they
use the current data and the proposed additions to that data, so that a
cost/benefit assessment can be made.   At least some of that justification
should be included in the final document, since one purpose of that
document will be to convince non-reporting entities to begin sending
reports.
