I can't comprehend the relevance of your words since we're not dealing on the 
level of "local-part" in this WG - only on the level of "domain".  Isn't this 
true?

There might be policies associated with the local-part of the  
referencing email-address domain.  Depending upon how this policy is  
being used, it may be required by some protocol to obtain this policy  
record.  Assume this would only happen when the email-address domain  
is considered trustworthy, and that there might be conditional  
constraints that might be applied, such as those that may pertain to  
the local-part.

Not everyone within any domain should be assumed trustworthy.  When  
attempting to define a protocol for indicating an additional level of  
trust, there might be a need to further constrain the assertion.   
That additional constraint would be required even when the signing  
domain matches the email-address domain.
