What's the point with that quite lackluster story in Endwalker?

[Rulakir]

As stated, the sundering is already responsible for the deaths of trillions. Even if the remaining ones were combined right now it wouldn't come close. I often wonder of the two who has the higher death count, Venat or Meteion.

I’d rather eventually the world come together again at some point in the distant future rather than staying incomplete and fractured due to one crazy persons mistake. It seems weird to just keep everything broken and unnatural.

Words cannot express how much I hate the concept of the sundering. I was "the world and everyone on it is incomplete" before we heard that from Emet and firmly #TeamRejoin until I started getting Hell for it. It wasn't even a mistake, it was deliberate and our WoLs exist as a consequence of this crime against mankind but, sure, make us BFFs with Venat because that makes total sense. -_-

And as for the Oda quote, it's the below:

Interesting, so that was as recent as 5.0.
