Good point. On first glance it seems unfair, but is it?

Sometimes the difference between a success criterion and a statement of
goal a little too subtle to  put in the original proposal.  Probably
something like, "capable of supporting a responsive style specification,"
would be most accurate. In that context it is entirely fair to expect that
level of accessibility. It is akin to requiring semantic markers and well
define reading orders.  At first it was an odious task; now it is routine.
Well, its time to do some more heavy lifting. We missed this before because
we couldn't see it.  Now we can. We know how to fix a difficult problem for
people with disabilities we missed in WCAG 2.0.

When pressed by market pressure the industry acted with remarkable speed.
It created a solution to small capacity view ports.  That technology
exists, it is time to move standards to match the change in technology. The
intent of responsive design was not to help people with disabilities, it
was to assist view ports with disabilities.  The technology clearly treats
a disability. We need guidelines to support its use so it will assist
people with disabilities.

It is time to list responsive design that aids enlargement and other text
customizations as formal assistive technology that assists partial sight
and other disabilities that benefit from visual flexibility. It is the best
AT for the majority of low vision that has every existed.
