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

[Turtledeluxe]

The "glimpsing the past" version of the Echo is the only one we've ever actually seen anyone using in the MSQ proper, and while it's suggested we have a particularly keen ability to do so (Krile mentions that the shared vision of what Estinien experienced back in Garlemald wasn't quite as clear as ours), there's nothing that suggests it's a rare trait.

There's nothing in the cutscene that was linked or in thr game that indicates Ancient's "casually view the past". In fact it's the opposite, the game is full of evidence from Hythlodeus statements to Fordola to Lahabrea that the Echo can be used in many different ways.

Even if the link did prove that, even if all the Ancients did it, the rules of peering into the past wouldn't work on Hythlodeus and Emet because it's not in their memory. So you'd have two conflicting versions of events happening, plus an Aether altering element in the mix with Kairos.

Also no it isn't the "only way we have seen anyone use it". Why are people liking these posts??? Zenos literally used it to body hop and its discussed at length. Fordola used it to anticipate movements in combat. The echo is not exclusively a past viewing mechanism-- it's a power derived from the Ancients that allowed them to manipulate reality. But as Hytholdeus tells us, they have all kinds of specific talents.

If it's so obvious that all the Ancient's casually view rhe past, then where is the in game scene confirming that. Does anyone other than Venat talk about it? Does Venat tell us it's casually done? She tells us how she uses it and teaches us..something that then goes down the line of her followers.
