I would even go so far as to say it was the opposite for Morihei. It is my understanding that Onisaburo encouraged his followers to use what they were good at and interested in and make that the vehicle of their spiritual practice. It is my impression that the spiritual was by far more important than the martial, the quote of dressing the old bujutsu in new clothing and all.
I think that Morihei was a lifelong follower of Onisaburo's, who, like any good teacher, encouraged his students to become independent of him. It is now obvious that the Aikikai severely downplayed the influence of Sokaku Takeda. I think the same was done of Omoto.
