New types of river biomes

I think it would be really cool to get more types of river biomes, because as of right now, there are only the river biome and it’s frozen variant. I think it’s about time we changed that. I have a few ideas of some different types of rivers that could be added, the first being the rocky river. I think it would be cool to see some rivers with, instead of a sand shore, a gravel, cobble, or stone shore. I think it would also be cool if there were stone rocks that would poke through the surface of the water. Another possible river could be a lush river, with more plant and animal life. The last idea I had for a new river biome was the muddy river, as I think it would be an easy way to get mud.

I also like the idea of water falls being added in general, as I think it would make some natural areas look better, especially with water shaders. Another idea I had for rivers is making different types of rivers more common in different places, or making it so some river will only generate in specific biomes. Like what if rocky rivers were more common in taiga biome, lush rivers more common in forests or above lush caves, muddy river more common near mangrove swamps, and waterfalls more common near mountains and hills.

Over all, I think Minecraft would be a little bit better with the addition of more rivers, as it adds more to traveling, especially early game if you are traveling by boat. I think more rivers and river feature will be a really cool new feature, and I hope you agree with me.
