Define 'now', because Endwalker itself had Urianger have a very visible crisis about the fact he just keeps having to lie to people and wants to stop doing that. The thing is that the Scions have mostly had their big character development things in the past: Alphinaud in late ARR to Heavensward, Estinien in Heavensward with a decent amount afterwards, Lyse in Stormblod, Thancred and (to a lesser degree) Y'shtola in Shadowbringers, Alisaie in 5.x. Endwalker just wasn't really a time for that for most of them, partially because they've already had those developments and partially because Endwalker's story is very external and doesn't really put them in those sorts of situations. And, again, Urianger still found the time, and I wouldn't say Endwalker was a footnote for the twins either. And if we're only talking about 6.x? Well, there's some clear development for Estinien and Y'shtola, it's just not 'disagreements' or 'challenging their ideals' and more about them figuring out what to do after that whole 'saved the world' thing.
But fortunately, one of the very few things we know about Dawntrail is that it's leading with a situation that causes a divide between the Scions! So if you want interpersonal drama, you're getting it, and it'll probably be good fun!
