Could you add netherite shulkers to this mod, or another one?

As far as I know a mod released shortly after this mod has done this and I want to keep this mod simple.
Netherite Shulkers

I will think about it but most likely no

That Mod is for fabric. Would you be willing to make a netherite shulker mod for Forge? Forge does not have a netherite shulker mod yet, and it seemed like you were the closest to inadvertently completing one.

I agree with you that this mod should probably only contain Nether Elytra.
