It's failed on Mimihagi at Yhwach's own admission due to it being a part of the Soul King. And Yoruichi's wires meant nothing to him, so why bother doing anything about it? Yes, I know that he had the surprise exclamation point and all that. And now we have Aizen. I would hardly call that inconsistent, especially "for the sake of plot". Mimihagi was notable as we are introduced to the only thing (that we knew of at the time) that could get passed The Almighty. There was ultimately no point in Yoruichi doing her wire thing, so I definitely wouldn't call that instance an example of The Almighty failing for plot reasons at all~
