No, they probably don't have more urgent problems. Sites choose not to 
adopt DMARC for a variety of reasons. It's probably a good idea to 
respect that variety.

The model that a receiving site is not allowed to report DMARC traffic 
unless that site is also generating DMARC authentication is 
Procrustean.  And as I noted, is likely counter-productive.

I understand the zeal that drives a lot of the effort to promote DMARC, 
but the danger with aggressive proselytizing is that it changes from 
serious technical and operational evaluation into purely religious fervor.
