The latest WCAG 3 draft was released a few days ago. Having read it, I do have some general comments. Mostly I miss the obvious traceability from the POUR principles through to success criteria, at least based on what was in the draft I read.

What is there, reads like a cookbook for designers and developers, rather than requirements centred on the user. I like cookbooks but I'm not sure they make good standards.

A longer consideration:
