If I understand your proposal, I think it's a more radical change to the 
guidelines structure than we'd want to do in a dot-release to WCAG 2.0. 
As a dot-release, I think we need to stick with the principles - 
guidelines - success criteria model, or it won't be sufficiently 
backwards compatible with WCAG 2.0. That does indeed create constraints, 
and is one reason WCAG 2.1 should be viewed as an interim release, not a 
"solve all the problems" version. I'm almost positive we'll want a 
different structure in future guidelines, which is what the Silver task 
force is working on.

My thoughts on cognitive accessibility "pillars" admittedly "shoe-horns" 
them into the SC model. It's not perfect, but it's an attempt to get 
some progress in 2.1, within its structure, with the expectation that 
we'll be able to do better in later guidelines releases.
