Can you clarify what IESG concern this is attempting to address? I looked at the IESG evaluation record for the draft (https://datatracker.ietf.org/idtracker/ballot/3084/) and didn't see anything that this change would address, except possibly Cullen's comment that he asked three developers what c

Okay, I would like to keep what we have, removing pieces is not a good idea, people don't have to use the tags if they don't want to and we MAY have a need for them in the future. The tags were discussed at length during the original draft. Removing them after the fact doesn't help or hurt adopt

This text inappropriately makes a normative requirement on reputation systems. Reputation systems are explicitly outside of the scope of our charter. As well they should be as there has been no discussion about reputation systems may or may not find useful, let alone require, from DKIM.
