Badges update automatically and link to the data pack page on MineUniverse.
This datapack simply ensures player head blocks copy their data (name, note block sound, etc) to their item form when mined.
This is useful if you have custom head items in your world (spawned via commands or otherwise) and want them to be consistent in survival.
This is unnecessary is you have a datapack that already does this such as VanillaTweaks' More Mob Heads.
