DKIM has nothing to do with reputation, reputation providers may want to
use DKIM as part of their processing technologies but that is their
issue/point of failure. I want something that allows me to accurately
identify who decided to send me a piece of mail.
What I choose to do with that identification is internal to me as a
receiver.
Any negative assertions by the DKIM signer may be helpful for me to
classify the material I have received.
Thanks,

This is how I'm thinking, as well...if senders try to piggyback on
somebody else's reputation, I'm likely to ignore that and use other
criteria to determine the overall reputation of the message.
The desire from some of the bulk senders & 3rd party reputation vendors
appears to be to allow a sender to say "go ask [vendor], they'll tell
you how good I am." This is not, however, something that receivers of
that mail would necessarily want.
And just from a general cleanliness perspective, I'd rather keep all
reputation decisions out of the signing/verifying process.
