Can you post pictures of the revised version?
If it's the version I think you're talking about (and the one that's connected to my Mac right now) I have my doubts it will do anything. The "strain relief" consists of about a centimeter of an extra layer of thick plastic tubing that's uniformly stiff and doesn't give way much on its own. If anything, all it will likely do is extend the cable's break point by about 1cm.
