Coconut Bomb/Grenade added with Palm Trees into Minecraft

Mojang have said that they will one day add Palm Trees into Minecraft with a desert update and most people want coconuts to be included with the tree variant. The coconuts would be solid blocks in the world that would have to be mined like melons and pumpkins and when it is it will drop a cracked coconut that can be drunk like milk maybe even also canceling poison like milk plus stopping hunger. The only way to get a coconut seen the way it is would be to use silk touch. I think it would be cool if after using the cracked coconut (drinking the milk) that it will leave behind a coconut shell. 2 coconut shells, 1 TNT, and 1 redstone would then make a Coconut Bomb which could be the equivalent of throwing a TNT since TNT must be placed and lit on fire. The bomb wouldn't immediately explode, same way a TNT doesn't but the time to get away from it should be short. There can also be different types of Coconut Bombs. Like a blinding bombs (using Ink Sacks), sticky bombs (using slime balls), smoke bomb (using sugar and dye) or even a Coconut Launcher that shoots these coconut bombs. I hope that others think this is a great idea and gets attention because I would really be into seeing this in the game. Thanks for taking your time to read my idea. I dont know if to include this in items or biomes btw.
