An Idea for Emerald Armor (Luck Effect Set Bonus)

So currently in Minecraft, there is no emerald armor or tools. A lot of people have said that they want emerald armor in the game. However, Mojang has stated that they don't want to add useless armor progression to the game. But, Mojang has also said that in the future they want to add more sets of armor that give you special effects if you wear a full set (like Netherite armor giving you fire resistance. Also in the game, there is a currently unused effect called luck. Luck makes it so that when you open naturally generated chests, you have a better chance of getting good loot, for those who don't know. Currently, there are potions of luck in the creative mode inventory, but there is no way to get the effect in survival. This idea addresses all of these things.

My idea was that emerald armor would have about the same stats as iron armor, maybe a little better. However, when you wear a full set of emerald armor, you would get the luck status effect. This would be a fun and useful mechanic in early to mid-game, and could be helpful in late game for getting loot from structures like the End Cities. This would also be a good way for Mojang to implement a feature that a lot of people want while also making it unique so that it is not just another set of armor, and at the same time adding in a fun and helpful unused game mechanic.

Maybe emerald tools could give you a little xp when using them, which would be helpful early game. If you have any ideas, put them down in the comments.
