Elder Guardians are not using Guardian loot table as base loot table

The bug

Elder Guardians are not using the loot table of Guardians as base loot table instead they contain nearly the same entries except that it is more likely to get fish instead of prismarine crystals (I do not know if this is intended). This makes it possibly harder to maintain the loot tables because normally an Elder Guardian should drop the normal loot of a Guardian as well.

Possible solution

To solve this, the loot table could be changed to the following, this would however remove the difference for the weight of fish.

{
    "pools": [
        {
            "rolls": 1,
            "entries": [
                {
                    "type": "loot_table",
                    "name": "minecraft:entities/guardian",
                    "weight": 1
                }
            ]
        },
        {
            "rolls": 1,
            "entries": [
                {
                    "type": "item",
                    "name": "minecraft:sponge",
                    "weight": 1
                }
            ],
            "conditions": [
                {
                    "condition": "killed_by_player"
                }
            ]
        }
    ]
}
