Splash/Lingering potion of milk and useful water bottles

We all know in pvp if youre a macer and someone slow falls you then youre just gonna wait out the 30 seconds in the air right? 
The only way to counter slow falling effect is milk but lets be honest, who is gonna carry around a shulker full of buckets of milk?
Here is my idea:
Lets add Splash/Lingering potions of milk!
It might sound too op but dont worry I already made a counter.
How to make Milk potions:
In order to make a potion of milk you will need to place a milk bucket in the brewing stand as a ingredient like how you make other potions BUT the glass bottles on the bottom cannot have water in them! (of course it needs blaze powder to work)
Once the milk goes into the bottles remove the empty bucket and you can upgrade/extend them like normal potions (No needed to make them awkward potions)
When you drink/splash the milk potion you gain an effect called "Nullified" which works diffrent on each level of the potion.
Milk potion I: 2 minutes (Wipes all effects and doesnt allow any to be applied on you until the effect ends)
Milk potion I (Extended): 4 minutes (Same as the normal version of milk potion I)
Milk potion II: 1 minute and 30 seconds (Deletes ONLY negative effects such as mining fatigue/slow falling etc.)
You can use those potions on yourself OR on your enemy
Counter:
So bottles of water are literally useless.
In short if you throw them at your enemy, they lose ONLY the Nullified effect.
Water bottles are one use without an effect for a bit.
Both pots dont stack!
