Your reading of the archive shows rather more complete and definitive discussion than mine. In fact I read the archive as tending in the direction of changing the specification to use Sender: rather than From.

Would you please explain the basis for assessing that this topic got sufficient discussion and that there was rough consensus on it?

Since this specification modifies RFC2822 that fact needs explicit justification.

The current SSP language modifies RFC2822, and so there should be considerable clarity about the need, the benefit, and the impact.

Indeed. I don't like that "1st author" bit.

If there are multiple authors, then whichever one is also the Sender should be the one that the signature should relate to.

If the Sender is none of them (the secretary sent it on behalf of them all), then there is a problem. In that case I might be happy for the Sender to match the signature, or even to go back to a "first author", though I don't really see what is wrong with an "at least one author".

It the Sender is absent with multiple authors, then the message if not RFC 2822 compliant, and all bets are off.

And if the signature is "restricted" (by g= or whatever), then the rules might be different.
