Yes. Evaluators need to use much more sophistication, when applying DMARC, than simply applying the formula and doing whatever the policy suggests. Developers need to provide exception mechanisms which permit that complexity to be implemented as local policy. This means we need language to

Re: [dmarc-ietf] Collecting message metadata, was Time to work on failure reporting
