My intent was to define criteria for selecting practises that we specify
and assert constraints based on potential impact.  In other words, we
should specify features that are likely to get used and that are not
likely to hurt individual sites or overall Internet performance.

(These sound like obvious criteria, but my own view is that they have
not been considered much during the discussions so far.)

So:


      Potential DKIM signers wish to assist receive-side message 
evaluation systems by publishing information about the messages that 
they originate and possibly sign. Criteria for working group selection 
of practices to specify MUST include a strong indication that 
receive-side processors have an interest in using the information and a 
technical assessment that the publication and query activities will not 
impose excessive burdens on clients, servers, or network nodes.
