Bundle no longer obtainable without using cheats

If you go into creative and search for bundle, it is not there. You also cannot craft the bundle. But, in Experimental Snapshot 7, you can. It is in the creative menu. You can craft it. Just not in snapshot 21w37a. The first two screenshots are in experimental snapshot 7 and the last two in 21w37a, as you can see by the debug screen.
