crossbow's and pearls

a crossbow extension, it could work like this,

a crossbow extension could be crafted at a fleching table and allow you to fire a pearl or potion at the speed of an arrow, but at a cost, each time you fire, it's consumed, i think it's balanced, they could be crafted out of sticks, string and leather. they could only stack to 16 so you can't carry a lot of them.

it's a feature that was missing from 1.14 and be useful in 1.16, because in the nether, you need to get around, and this could help, so when you throw an ender pearl, you don't need to ask a particle physicist to calculate the angle so you don't hit the edge of the plateau and fall in lava. and it could give a use to the fleching table and keep leather farms useful in the late game.
