If I understand Takahashi S.'s article, he's saying that just letting each student figure it out for themselves hasn't worked. So we need a way to train it explicitly. So your first question might be rephrased: Is there an ideal way to train these skills for Aikido? Should that be to any degree standardized? And what is that ideal way?
Well since it's an Aikido general specific board on an aikido forum I figured asking specifically about aikido to be even more extra redundant
