I send nothing is much more categorical. The data can go straight

But surely if you assert "I sign everything" then any mail that is
unsigned (where "signature corrupted by mailing list" is identical
to unsigned) should go straight to the bitbucket.
Or are you suggesting that an email from a sender who
"signs everything" that arrives with an invalid signature should be
treated as valid? If so, DKIM+SSP is worthless. If not, then the two
assertions are identical in result.
(One may consume a little more CPU than the other, but that's
really not going to be an issue, for the obvious reasons).

SSP is not very relevant in this case as that spec is not on
standards track and DKIM is.

I've always wondered why dkim is taking on the task of
supporting "I
don't send mail" since the statement makes no reference to
signatures
at all. Arguably, that's something that should be dealt with by
someone else, who might also think about saying "I only send mail
that's less than 1MB", or, "I only send invoices".
Especially since one can achieve that same effect by having
an SSP that says "I sign" everything and then don't sign any email.
