And given what Urahara said about the effects of hollow reiatsu on Quincies. That it can cause either permanent damage or even soul destruction, one would assume that if that rule was absolute, then Yhwach would kill all he could find.

And not hold Harribel a prisoner like he did. Recruit them as he did. He even said to Haschwalth that they could always create more Arrancars. So either Kubo messed up, or there's something not adding up.
