Maybe it needs to be less subtle, I'm not sure. I feel ok with putting it back but at the same time I'd prefer for us to be able to define the focus style as otherwise it limits us going forward. It seems to be reasonably accepted that a different style can be used instead of outline: http://a11yproject.com/posts/never-remove-css-outlines/ http://outlinenone.com/
