It's not only not crucial, it's entirely resolved, and always had been, 
in terms of real-world practice. The view that it hasn't been is frankly 
an arrogance of author domain owners.

Author domain owners do not have a relationship with receivers or 
recipients, so their policies have no enforcement potential. Receivers 
and recipients are completely independent.  They do not 'override' the 
domain owner policies.  Rather, they apply their own policies.  Always have.

This is why the language in DMARC would be far more constructive to 
remove any hint of attempting to direct receiver or recipient behavior, 
and instead merely reflect the domain owner's assessment of message 
validity, along the lines of the language I offered.
