We can't even define what we are talking about here; it is complicated and difficult to train it, it is just as hard to describe what it is. People are still talking around the actual training methodologies on this forum. If you want to change Aikido to have This Stuff there needs to be writing about it, pictures, videos, all of that.
You know, I teach English (and Japanese) and English teachers still can often not agree on what is or is not a good or a bad essay. Their opinions differ vastly, but, they continue to teach and test all the same. It's normal. Maybe for Aikido, it could be the new normal.
