I added the bundle crafting recipe. Yes, you can get this by going into the "experiments" tab on the create new world screen but this one makes it easier to get on a server and it comes with a shiny little advancement that you get upon crafting a bundle.
Just pop this in your world or server and you're good to go!
(In case you were wondering, the recipe is the same as it is the experimental datapack. 6 rabbit hide and two string.)
