A lot of interesting comments on the thread, but my point in the initial thread has become more apparent in the discussion.
As I stated, the original students of O’Sensei, after he died, all went off and started teaching their own interpretation of what O’Sensei had disseminated.
All except M. Saito, who stated repeatedly that his focus on training was to preserve the techniques the founder had left in their form before the founder died.
Virtually every student of Ueshiba that I've ever trained with claimed to be teaching exactly and faithfully what the founder had taught to them. That includes Kisshomaru.
OTOH, I heard Saito say clearly that there were things that he had changed - don't just take my word for it, it's in some of the public interviews too.
