I don’t have a particularly large stake in this as I am increasingly on the “wouldn’t it be crazy if I replayed Morrowind again” train but going by (obligatory: Fuck fandom)

fallout.fandom.com/wiki/Fallout_4_next_gen_patch#…

Looks like a somewhat decent amount of scripting and placement changes that would definitely cause merge conflict level issues with mods. And enough code changes that it would break the script extender.

You can make the argument that you actively don’t want those fixes but… considering the shitshow that the “unofficial patches” have become, being able to play more “vanilla” holds a lot of appeal to people.
