Why do you simplify handling of list mail to sorting and filtering, 
ignoring two other important list handling activities:

1. reading mail
2. responding to mail

In both activities the From address (and possibly other fields like 
Reply-To and Sender) plays an important role. From a recipients point of 
view I'm not interested in what path the mail of John has travelled to 
my Inbox. And maybe the question boils down to what is DKIM: are we only 
interested to asap jump from DKIM to domain reputation, or do we also 
see the domain assertion statement in the DKIM spec:

   The ultimate goal of this framework is to permit
   a signing domain to assert responsibility for a message, thus
   protecting message signer identity and the integrity of the messages
   they convey while retaining the functionality of Internet email as it
   is known today.

I fully agree.
