For two reasons
>they realized that shoving important lore into random descriptions and not the main story meant most of the playerbase was completely lost it
>they focused so much on filler festivals/characters, that many plotlines set in said descriptions never came to fruition
That's why Nod-krai is basically a review class of Genshin's lore to set up the base for the story's climax with the Tsaritsa and Khaerianh.

As much as I was pissed off at us getting a filler region at first. Now I think it was for the better because Scheznhaya in 6.x would've been a rushed mess to cover these mistakes.
