I note too that e-mails in unusual dialects appear to get footers added

I believe that this does not invalid the origin DKIM signature, so I see
the criterion as always modifying messages but not in a way that
invalids DKIM signatures.
That modification invalidates the DKIM signature.

There is a BCP for mailing lists. The IETF
document was not aligned with the Mailman common
practices at the time the IETF document was written or now.
The stress, if I may call it that, today for
DKIM is that the signing is not in sync with how mailing lists are run.
Yes.
