Idea to improve Microbiomes in Experimental Snapshot 3

Microbiomes kind of make areas of Minecraft worlds too busy or weird looking. For example, finding a tiny desert inside a forest, or a strip of forest cutting between a taiga and snow plains. I think it might be better if microbiomes had to match the biomes around them completely. Normal biomes don't have to match surrounding biomes, and that's a good thing. However, it's not as good when microbiomes don't match.
