Rural versions in the US are typically wide enough, unless they're dirt or were last paved a generation ago, but those properties tend to mean they don't have a consistently defined edge anyway, and often that they're shared between occasional farm use and people driving trips that are recreational and not just "late for work"
It's much more about attitude than infrastructure, and Europe seems to have much more expectation that color between the lines will actually result in it. In the US it's recognized there's a need to look at all the cues prompting behavior.
My first thought about this arrangement is that basically it really isn't a change from the cyclist's perspective. All that's really been done is they've painted in the FRAP zone. From the various studies that you can follow to through the links in the OP, there's little or no evidence this has any effect either way on bicyclist safety..
