I recently managed to once again muck up crafting something with multiple unstable ingots (from Extra Utilities) and ran into the issue where the first exploding ingot kills you, and then the remaining ones end up inside your grave, ready to insta-kill you as soon as you attempt to recollect your items -- the subsequent explosion(s) likely destroying some of your items along with you.

This made me feel it might be a good idea to add a configurable blacklist of items that should not be stored in graves on death. I can also think of some other use cases for this feature, e.g. making specific items significantly more precious/risky to use due to real risk of losing them on death.

Preferably such a blacklist would include the ability to flag whether a given item should dropped on the ground on death ala vanilla, or whether it should be outright deleted.

If this idea is too complicated for now, just blacklist by default at least unstable ingots made from iron ingot (not from iron nugget that will not explode) please, cause that bug will really make my players complain about graves and ask me to re-enable the gamerule /keepInventory if this happens to their.
