The ability to combine potion effects in cauldrons.

Hello everyone. This idea was mentioned to me by a friend and I thought it was a fantastic way to make "stackable potions" and also solve some inventory problems player might experience. The idea is that you can put your potions (of any type) into a cauldron and when you take a bottle and use it on the cauldron, the resulting potion in the bottle would have the effects of the the original potions combined. For example, say I put potions of Slow Falling for 4 minutes, Fire Resistance for 8 minutes and Strength II into a cauldron, the potion would have all of those effects. I think this would give some more uses to cauldrons, and also be an opportunity to bring some parity features from Bedrock Edition to Java. I realize that this might be difficult to implement and might have to be tweaked slightly, but I think it would be really cool.
