Did Ueshiba Morihei ever teach ukemi? If "I" (as the generic student) have to "figure it out yourself" then how can my teacher take credit for my efforts?
I'm not sure that's an argument one way or another. A huge percentage of the things I've learned so far in aikido, whether as uke OR as nage, have been learned more through interaction than through explicit instruction or 'lessons'. Particularly if I train with someone senior to me, I inevitably learn all kinds of things whether they're 'teaching' me or not. I'm finding this to be more and more the case lately.
