A counter-argument is the classic "Don't let perfect be the enemy of 
good".  DMARC works well for a very popular -- albeit very constrained 
-- scenario.

For any mechanism, there is always the possibility that someone will 
apply it for scenarios beyond what was originally envisioned.  Often 
that is a large benefit.  Often is not always.

The distinctive issue now is that that extension is being done by very 
large players.  The phrase "Too big to ignore" has been rattling around 
in my brain for the last few weeks...
