The current guidelines were fuzzy enough in places, anyway. The new ones seem to be more centred around the user's 'experience', and less around the mechanics underneath the pages. I have no idea whether I'll spend more time, or less, crying over checklists as a result. (And whether they'll give me further ammunition to get the more jarring elements of the site cleaned up, and get a section up for people with learning disabilities, and all the other things I want to do. I suspect not, because we have no time nor money.)
