To add to this for folks:  Murray and I have in fact been considering 
developing 
an added canonicalization scheme that is relatively more robust against a 
broader set of things that cause breakage.  His OpenDKIM has been developing 
some data about a set.  The list behaviors are part of that.

We haven't gotten into the technical detail yet.

While I also think that's interesting to explore, I'm not so enamored of it 
yet, 
largely because I see it as likely to be too messy to be practical at scale. 
But that's just intuition.
