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

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.)
