As suggested in the interim meeting I put together some proposed language to clarify the forwarding/intermediary use-cases. First PR <https://github.com/dkim2wg/spec/pull/12> just updates the language to be more explicit around re-starting the chain and what "must not forward the message" means. The second PR <https://github.com/dkim2wg/spec/pull/13> defines body-authentic so we have shared language and definition around the modifying without munging case. It does not define any handling based on the case but this will allow us to have the discussion around updating DMARC with a clear definition. Note, that it does ignore changes to the Subject, which seems okay since those are less likely to generate phishing risks.
In terms of handling forwarding cases during the adoption phase, I do think that Wei's draft on localized header fields <https://datatracker.ietf.org/doc/draft-chuang-dkim2-localized-header-fields/> will be helpful to support complex multi-hop forwarding cases. Having a versioned history of authentication-results is nice. But, to keep things simpler it should be enough to lean for now on Bron's (hopefully soon to be adopted) Authentication-Results <https://github.com/dkim2wg/spec/blob/main/draft-gondwana-dkim2-authres.mkd> for the majority of forwarding cases.
