Disagree, because you went at it half-hearted. You made it 
experimental and your abstract even stated that it probably means 
nothing. More importantly, Levine and Crocker didn't support the 
effort, so it didn't have a chance at all.

Its call marketing just as it was done with DMARC which is less 
flexible than any other policy system.  If you don't champion it, it 
goes nowhere.

It was already discussed. Unless you are sharing this "Whitelist" in 
some centralized fashion, it won't be a persistent and consistent 
protocol solution.  What it will promote is targeted abuse at those 
sites that do not have the same whitelist -- You ware making it so 
that "Batteries Required" in order to function.

We been thru this already.  We need a standard consistent and 
persistent domain based solution all can apply equally and one that 
you don't need to buy "Batteries" to get any payoff.  Even with all 
the "small use cases" belief that is being proven wrong about policy, 
you guys are still in denial about policy.   Everyone is telling you 
guys you got it all wrong, and you still won't listen. This thing will 
never be solved with a status quo.
