Great observations. I still think we need to be careful that we don't try to fit IK into every case. I am obsessed with him, but that doesn't mean he was responsible for every case that has some commonality. Unfortunately there are no shortage of 'bad guys'! This isn't a criticism (after all, I am the one who raised this possible connection) just a caution, perhaps mostly to me. What is that old expression? ..."if all you have is a hammer, everything looks like a nail" But there are some coincidences that warrant further investigation!
