Coasts and oceans update

The next update Minecraft should have is to improve the generations of the ocean and coastlines. For the update, do what was in the cave and cliffs update and make the oceans 2x deeper . make coastlines longer and bigger. Add new structures like lighthouses, generations like sandbars and underwater cliffs. This would add a lot of exploration for both of these biomes. Something that would also be cool to add in this would be ships that the player could captain. We already see them of the bottom of the sea floor I don't see why we can't steer them ourselves
