Any other sort of re-posting does not qualify, under this definition.

So, for example, anything depending on 're-signing' is not a DKIM Replay

Yes?
That's my understanding, however that scenario also describes a normal mailing
list if it doesn't make modifications that break an existing DKIM signature or
any kind of forwarding with similar characteristics.


Indeed. Noting that benign re-postings look the same would be a requirement for the PS.

(As the current and future drafts do.)
