Loot table item count setting

I know you can easily code it by yourself, but a feature would be cool:

minimum and maximum number of Items in an Itemstack per Roll, In Vanilla LootTables like this:

...
                    "name": "minecraft:arrow",
                    "functions": [
                        {
                            "function": "set_count",
                            "count": {
                                "min": 2,
                                "max": 7
                            }
                        }

...

Would be cool if it would be a normal feature in loottable mod creation
