Right-click with an empty hand to catch a splash potion

Okay, I've just thought of this idea so apologies if there is some quite glaring drawbacks I've not thought through but here's my idea: catching splash potions.

My idea is if you right-click with an empty hand on a thrown splash potion, you catch it. If splash potions are or become prevalent in combat, it can add another layer to it. Alternatively, when playing with friends you could hot potato a harming potion about or even single-player effectively do keepie-uppies. I don't think it is gamebreaking, allows for another bit of fun and more importantly, witches annoy me so it would help me out there (/s)

I did think about applying it to all projectiles, i.e. catching skeleton arrows or ghast fireballs but they seem a step too far. It's easier to catch a bottle thrown at you than an arrow shot at you or a flaming chunk of fire.
