Updated comments on WCAG3

Sorry these comments are late - I wanted to see what other folks posted.
My gut feeling is the main issues with v3 are inherent to the
'accessibility guidelines' model and can't be fixed within those confines.
After reading the thoughtful responses, I am even more convinced of this.
This comment (posted by Claire Grupe) sums up the problem:
"The guidelines specifically note that WCAG 3.0 is designed to improve the
usability of the web for those with certain disabilities and limitations.
We recommend emphasizing in the literature that good overall usability
guidelines are not covered in WCAG; that the inherent usability or
conceptual model for a process or workflow is covered in usability for all
users, and WCAG's guidance ensures that this overall usability is
extendable to all audiences.* As it is currently written, it is unclear
that overall usability is considered a minimum baseline requirement*, and
may be potentially confusing."
This is the Catch-22 of defining accessibility in terms of disability
access rather than overall usability, and this is what I address in my
paper.
Thanks for your time,
