Add Cliffs

When a Caves and Cliffs Q&A was released (please don't ask me which one), one of the questions was "Are you going to be adding cliffs, or just mountains?" and Agnes Larsson (@LadyAgnes) replied that they were mainly focusing on the mountains because they won the biome vote and also Caves and Cliffs sounds better than Caves and Mountains. But why not add cliffs? I mean obviously there are edges like in the bamboo forest having an open cave underneath and staring off into an ocean, but there aren't actually any cliffs. But this would make the game SO much fun! Like staring off the edge of a cliff and having a goat ram you off, or a player push you off was exactly the kind of fun adventure that Mojang wanted players to experience! Anyway that's just my humble opinion :)
