Extreme world generation

It seems that the snapshots have some extreme terrain generation sometimes in the new biomes. I used regular terrain generation (not amplified) to have a look around at the new biomes and found this rather extreme bit of savanna plateau with floating parts everywhere and going really high up. I kind of doubt that this is as intended in non-amplified world generation. My apologies if it is (and enjoy the seed in that case, it's pretty amazing)
