I don't believe the supposed "stop down focus shift" is a design flaw, but probably a manufacturing problem with some of the lenses, perahps only affecting earlier versions of the lens.

I got my 28mm F1.8G recently and after thorough testing I can confirm there's no stop down focus shift problem at all on my sample. In fact, it's one of the sharpest lenses I've seen, and improves all the way from F1.8 through F8.
