Would be nice to add support for modded shulkers. Reinforced Shulker Boxes to be more precise, since is a successor of Iron Shulker Boxes (which is still only for 1.16)

I second this, as it's also compatible with quick shulker and shulkerbox enchants- which is looking to add compatibility with shulkerbox slot when it updates to 1.19.3 (presumably 1.20 if it doesn't update to 1.19.3)

It'd honestly be like having mod that adds backpacks with upgrades, but still within the spectrum of vanilla.
