An Ocean Update

I think minecraft could benefit with an ocean update in both the overworld and the nether. The overworld ocean could go deeper, into a new biome called the "Deep Ocean". The deep ocean could have rare materials used to craft potions, armor, and diving gear to survive longer in the pressure of this new area. There is also room for new bosses and enemies, and new ores that can craft useful blocks and items. As for the nether ocean, it could have a little more danger, maybe hostile lava mobs beneath the surface that attack the player, and the only way to attack them is to get lava diving gear or potions crafted from deep ocean materials. The ocean itself could go deeper and have new structures that give valuable items like strider armor(to travel across the ocean safer), new items that are convenient, and a way to summon the nether ocean's exclusive boss(Maybe the blaze king👀) . The Deep ocean and the Nether ocean could both help in upgrading eachother, the diving gear for the deep ocean could require nether ocean items, vice versa.
