Doesn't it seem a bit overkill? Because it was never aimed at just those two. Remember, the existence of Momo and Kishiki suggests the rest of the clan is still around on their homeworld, possibly powered by hundreds of fruits.

She wasn't going to wave war on the vanguard, but potentially at an entire world of superpowered beings. That would make sense. So then that's what those places with the strange symbols are: storage facilities for stronger, fused versions of White Zetsus. Maybe they act as generals or something?
