When fallout 4 was in development, Bethesda had to crunch and have non-developers who had little to no experience in the engine (like writers) work in the creation kit to flesh out the rest of the game. This led to many quests being implemented entirely separate from each other with little to no input from other teams or staff members and is a major reason why fallout 4 base game feels so disjointed once you actually start exploring it.
It wouldn’t surprise me if they had to do the same thing with starfield.
