I tested this just for you, by downloading stable mode. And short answer; YES they are in both stable build and in Experimental. The debug console works fine. Enter "Biome" and the list of biomes will show on your screen. Here are the commands:
 * "Biome Waterislands" - Underwater Islands
 * "Biome Sparsereef" - Sparse Reef
 * "Biome Inactivelava" - Inactive Lava Zone

Enter them, and it will take the player to the place. More info about debug codes can you find by clicking here, and biome map here.

Do you have the game?

Cheers
