Add more variation to nether terrain

In my opinion, the nether still needs some work. And while it's leagues better than pre-1.16, it still has a long way to go before it's even comparable to the overworld. One way I've thought of to improve the nether even further is to have nether generation vary a lot more across the dimension. I'm sot saying you need to add new biomes (though a sulfur biome would be nice). I'm thinking something more akin to weirdness, or the cheese, noodle, and spaghetti caves in the overworld. Some areas could have round caves, others thin and narrow, and even others could have flat ones that are layered like lasagna.

I personally think nether generation could be a lot more adventurous or even down right bizarre. And I think a lot of the groundwork for something like this has already been made in 1.18.
