Yes, is happening. A new version of a year-old map of mine shulker box saves is being remade myself in 1.19.3. I decided that a whole year would be long enough to collect and stash a lot of new custom items, spawn eggs, Banners, and player heads. I'm sorting through all the items into chests with little item frame labels to help you know what's in each chest.
I have Beefed up my spawn egg collection with many versions of bosses for arena and worlds like smp7's Raids mobs.
Players heads is something I stay away from now due to them being easy to get and not as cool as some of the other items in this world.
