Response from the Working Group
There are assistive technologies that can highlight the focus or add
another highly visible focus indicator.  Common user agents can also do

For example in Firefox, setting the preferences
   browser.display.focus_ring_on_anything => true
   browser.display.focus_ring_width => 5
will allow override any page specified focus suppression and show a highly
visible focus indicator on any focusable element.

It should also be possible to do the same with a user stylesheet using

As a result Focus Visible is not at Level A.

But assistive technology cannot add order if it is not there, so Focus
Order is at Level A.
