Indeed. Noro Masamichi at least had the decency to change the name of the thing he ended up doing.
I would agree with this. If I recall correctly, Noro Sensei was involved in a car accident, he had difficulty for some time getting back to Aikido. He found he could practice the soft graceful flowing movements which he name Kinomichi. He doesn't claim to teach Aikido anymore.
