It’s great the developer invested and applied their time into the ineffably magnificent universe, title…
But, I do not believe the developers at Bethseda, Zenimax do lack ambition for it. They have professionals, much more sufficient and experienced for such a task, too.
Yet, they also are accountable and responsible for titles, history, and are expected to always stay that way, too.
Such a drastical change as you describe is indeed much significant… and that added to the official release assumes every single person will receive it, and those who remember it the way it was won’t have it anymore, and those who adventure the universe the first time - will have different than it was.
That is, it may permanently damage the initial, and now inscribed into the infinite history, presentation and shift expectations.
Changes like that may break connections between people, apply utter confusions, and insert gaps into the history enough to dissapoint everyone, where new state is now disconnected from the past experience.
Personally, I appreciate these transitions. The allow me to re-think and analyze future actions better. They add a pause that allows to reconsider the events.
These transitions are there for reason, and accountable, responsible developers, artists, people… consider it all, too, based on statistics or not.
