Change 1.4.10 to Level AA

Dear AGWG,

There is one thing you that would make a big difference for people with low
vision. Change Reflow 1.4.10 from AA to A. This can be done with WCAG 2.2,
we don't have to wait for Silver.

There are two good reasons to do this. It is vitally important for almost
everyone with low vision. It is as important to low as text-to-speech is to
blindness. The second reason is that the overwhelming majority of sightes
nearly meet 1.4.10. So, no cutting edge technology is required. It is dead
simple to make a case that works at 320 by 768.

The main reason AG got this wrong in the first place is that the Low Vision
support communnity grossly underestimated the print size needed to read
with low vision. The simple fact is that the print size needed to read is
almost a linear function 1/(visual acuity). If your vision is 20/80 you
need print that is 4 times as big. We already worked out how to make 400%
into 1000% by varying viewing distance.

The second reason everyone got this wrong is reflow itself. Almost nobody,
including me, realized that horizontal scrolling takes as much work as it
does. I was probably the most startled by my own discovery.

I suppose we didn’t make it Level A because we didn’t think it could be met
so easily. It can.

Moving it to level A would be to give it the status it needs.

Best, Wayne
