The Shredder is a complicated case, it has to be able to Recycle literally anything that has Material Data attached to it, except things that are already Dusts, or Stuff like Ore Blocks. That Recycling Part is what might end up preventing the removal of a Recipe.
And disabling the Shredder Recipe of something that can be recycled doesn’t make sense since the Crucible could Recycle it just as well and that one isn’t even configurable due to its complexity being even greater than any Recipe List can be.
So what Item do you actually want to remove from the Shredder and for what reason?
