Would be awesome if plugins could implement their own versions of RecipeChoice.
I understand that this is "illegal" from reading the JavaDoc, but was wondering why and if there was a different approach. Currently trying to add a recipe where an item needs a special NBTTag in crafting and used ExactChoice for this, but this sadly makes the item invalid if enchanted or renamed.

I've tried to do this with events, but this created buggy behavior when shift-crafting and was also quite a pain to setup when thinking about compatibility and more.
So yeah, to sum up, would be awesome if I could write my own predicate for ingredients in recipes so that I could check for a specific NBT value instead of an exact copy of an itemstack.
