I'm play 1.20.1 often,
About items:like Vanilla shulker box,Supplementaries's sack and safe.
Some modpack/customsize author like this mod but this mod haven't item blacklist system,And it's can avoid NBT data leakage caused by repeated storage of items with storage functions.

Container items such as backpacks and shulker boxes are marked as "This cannot fit into container items" in code already, and I'm already using it.

I will add the black list in case some mods forgot to use the flag.
