Allow rapid-throwing items by holding "Drop Item"

What:

Holding the "Drop Item" key/button for more than 0.75 or 1.00 seconds should allow a player to throw multiple items from a stack, preferably about one every 0.10 seconds (10 times per second).

Why/Advantages:

It'd be fun and harmless to just shoot out lots of items very quickly, and may allow people to give roughly half a stack of items or so to another player without having to open their inventory to split up the item stack first.

Disadvantages:

Unfortunately, someone will probably accidentally throw multiple items into lava by accidentally holding "Drop Item" for too long. That's inevitable. (This is why rapid-throwing should start after well more than half a second.)

"But this is already a feature?":

Not quite; In Java Edition, if you bind "Drop Item" to a mouse button instead of a keyboard key, you will only shoot out a single item from a stack, no matter how long you hold the mouse button for. This proves that the current behaviour is not entirely a feature yet, and is instead a bug related to keyboard input.
