There’s a LOT of under the hood stuff people havent really noticed yet. Armor Trims AND A DUMMY ENTITY with an ok level of default listening parameters is a massive step forwards for making the game more fun in the future.

Armor trims alongside attributes and NBT fundimentally allow you to make custom armor in vanilla. Armor trims let you target unmodified armor, and replace it with the armor you code in. If Mojang extends this to items, and give us some dummy trims, we could remake mods with data packs even easier.

The dummy entity is beyond crazy for plugin and datapack creators as well. I saw someone make a functional piano when the system first came out.

Will it replace modding? Absolutely not, but it will help improve mod performance going forwards for sure.
