The three I see mentioned are

   1. I sign all mail I send with DKIM.

   2. Someone else is sending mail with my domain in RFC822 From:

   3. I send no mail.

It'd be nice to see something fleshed out that shows the benefit
to sender or recipient in a real-world case in a little more detail,
along with a fuller analysis of the benefit SSP adds to the
scenario.

One of the most obvious useful uses for DKIM will be to combine DKIM
sender identity with a domain based whitelist in order to communicate
information about the message to the recipient.

Are you suggesting that this is off topic for discussion on this list?
