*Spoilers* The Past and After the Endwalker MSQ End

In short: Its a can of worms that is not worth opening, trust me.

Pretty much. It's been done before. There's no in-game reason not to as of yet. Some of the Studium quests also imply an ability to travel back in time independent of either the original travel facilitated by Elidibus or the memory crystal. Studium quests can take place either during or after the MSQ.

Yes and in my opinion it was a stupid one, they should have left time travel as closed loops like they already did with Alexander as whenever you open up the possibility of changing the past, doing anything else becomes redundant when you can simply solve the problem by going back and ensuring it never became a problem to begin with. It also means you can't have a story where you time travel without changing the past because then people will, admittedly understandably, complain about us not saving the past.

To be fair their world was VERY miserable and they were so desperate for a better world they were willing to potentially completely destroy their current timeline to achieve a better world for someone else, not exactly a state of desperation we want to duplicate. And my point still stands, we have no idea if our timeline even existed until they yeeted G'raha back.
