Biome & Structures generations

I feel like the minecraft world generation is still a bit messy and sometimes it generates chunks a bit badly and non really intelligently, for example: It happens to randomly see some strongholds in the middle of the ocean or a cold biome right next to a desert and it doesn't really make any sense. I would like this to be fixed because it would give the game a more interesting by fixing these generation problems and making them generate correctly and maybe not really bugged into the chunks like it happens alot of times
