We (almost) agree on what I think is the most important point.  Emphasis ** added:

GV> If the users who need high contrast cannot reasonably be assumed to have any assistive technology, then one **should not** rely on them having assistive technology in order to meet the success criterion.

Does WCAG say that one **should not** or **must not** rely upon AT for users who need high contrast but cannot reasonably be assumed to have any assistive technology?
