Thanks Jonathan. That is interesting about the focus rectangle. I've been
shown some pretty hard to read "focus states". While I don't believe there
is a WCAG guideline setting a hard rule for ratios regarding indicating
focus, I'll usually tell a designer who shows me a gray border, wrapping a
gray tab to go back to the white board.

Back to text contrast ratios: When it comes to AT, it's difficult to tell a
design executive who shows me the Darken Colors setting on an iPhone that
as cool as it is... it doesn't offset the 4.5:1 standard in the WCAG. Glad
to hear at least one opinion that the halo is a legit solution.
