You don't need eyesight to have vision.

LVTF folks...
there is an ongoing discussion on the AGWG and LFTF list see
http://lists.w3.org/Archives/Public/w3c-wai-gl/2018AprJun/0685.html and the
subsequent 18+ messages in the thread.
there is a closed survey
https://www.w3.org/2002/09/wbs/35422/non-text-contrast/results

There are 2 sides to the issue.
Narrow view: browser exemption applies only if the author leaves the :focus
in its default state. So whatever the browser displays as default is a
pass. The author is free to change any other colors.
Wide view: browser exemption applies only if the author leaves the :focus
in its default state and does not change any colors of an element that can
receive focus. For example: If the author sets
body {background-color: #fff;}
and, if the browser default focus ring does not meet 3:1 contrast, then the
focus state indicator must be set to ensure a minimum of 3:1 contrast.

If you have thoughts or opinions please jump in the thread above or attend
the AGWG call on Tuesday.
