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

That is her logic at the end of the day, only framed in terms of 'mankind'. Nonetheless, in my view, even such an alternative approach still focuses too much on attempting to justify the erasure of their kind, when the Scions reject Emet-Selch's own approach in doing so. Frankly, if they tried to justify it in that way, I'd probably be even less satisfied with what we got. IMO, the best way to deal with it would have been to simply have it be accidental/prompted by third party manipulation. The post-Elpis scene is weird, because besides being stylised/a flash forward, also seems to be referring to the second stage, given the state of the skies and the fact that it appeared by all indications that they were sacrificing themselves. That stage also happens to be the one that corrected the star to a functioning state.
