So, recently I've been watching the Minecraft series of YouTube, Hermitcraft, you might know of it. They have a datapack that allows them to position Armor stands and make them invis, for decoration on builds with the use of a book. It doesn't affect vanilla gameplay at all, and is purely for decoration. I think it fits into the theme of wildercraft, because it allows players to express their creativity through builds much more than before in builds, also for a little bonus, I think it could definitely help decorating spawn. I'd say it's a 1-2/10, I personally don't know how hard it is to add a datapack to a server, but yeah.
