I should have been clearer. That's what I see in a lot of what's out there now, which (I believe) has in many places degraded because of the stylized attacks. I've seen uke fully commit weight forward (still balanced, but weight moving further forward than necessary) quite a lot when visiting schools. It's an over-pursuit of one version of "aiki", IMO. I actually use two different definitions of "aiki" even in my own training. One is the "pure" version, which almost entirely uses the committed momentum of an attack. The other is more conceptual, and more in line with the "ju" in Judo/Jiujutsu, and is seen in a lot more arts. Both are useful, but an over-concentration on the first version leads over generations to a dependence upon that forward commitment. A "polite" strike doesn't have it. Nor does any cautious, controlled strike - the only strike I'd offer someone I knew was a competent grappler, until I had them off-center.
