My proposed text attempts to inject the idea that at least one
identity is an author authorized signer distinct from what is already
stated as an independent trusted identity.
But I don't think the actual "author" (in the case of this message,
me, the guy who's writing it) is involved in any way in the signing.
I certainly am not authorizing anyone to sign this message, and likely
don't know whether it will be signed or not. The DKIM model says
that's done at the domain level, independent of the author's wishes or
actions.
It's possible to have use cases where the author does decide, somehow,
whether or not the message will be signed, but I'm not aware that
anyone's doing that, or has plans to do that.
