The first case isn't legal, it's IMO no job for SSP to specify what implementations / receivers do with syntactically invalid mails. Invalid => do what you like (it could be first author). The second case is legal (ditto Resent-* and domain literals). I've no idea what to do, nobody here liked the proposal to use the PRA, many don't like to use the Sender (if it's not one of the From-domains), "toss a coin" (Message-ID or 1st author or Reply-To) is unconvincing => SSP has to give up, receivers can treat it like a single 2882-From with a domain literal.
