Call it a few bad apples spoiling the bunch in my case. I've had people do dimensional RP before, in other games, and they're (in my experience) the sort to always make everything that happens about them, how they're a stranger in a new land, and how they're unsure how to get back home. It's never a backstory for them, it's a frontstory, the thing that consumes them the most and detracts from any actual RP because we need to be constantly reminded that this ain't his homeworld.
All of those examples you name, Leanne, are meant to be colossal revelations by the way. The only people who know what happened with the timeskip are the 1.0 Warriors of Light. The only people who know what happened inside of Coil are the tiny party that traveled with the NPCs inside of it. All of the knowledge collected about Primals is limited to the Scions. In other words, the sort of giant special circumstances that would allow for these sorts of things are fairly considered in the hands of High Powered characters. There's more than a few of them telling stories here, but the sort of world-conception-shattering-plot reveals...
Do you know anything about Eldritch Horror? The Lurking Horror kind of stuff, the madness and insanity that comes from really, truly realizing that we are insignificant in the face of the vast cosmos and that our world is a mote in the black emptiness of space? When adventurers from dozens of other worlds just start falling out of the sky it's going to destroy the concept of the world for most people who buy into it. It presses hard on the suspension of disbelief that comes from playing a character set in a world: You either go "huh, that's weird!" and roll with it, or you do the opposite, wherein you realize your entire world can be taken from you in an instant because you happened to accidentally slip between the cracks of the world.
It isn't something that should be taken lightly. Cross-dimensional stuff gets into heavy territory. Remember, the NPCs during the Shantotto event put her appearance on the level of the Calamity. It's world-changing.
