example dimension, without the mod:

example dimension, exact same seed, with the mod:

personally i think it would be nice if this was a feature toggleable in json, because maybe if the dimension has overworld-like generation, the modifications would be a wanted feature, but not for dimensions with an entirely different style of generation?

Valid point. I do have plans both to make the terrain itself more faithful to Vanilla (just with its refinement in removing grid creases and increasing angular variety) as well as to implement some sort of system for when users/mods want to disable it anyway. I have a new version in the pipeline and I'm going to look at adding this to it.
