Uncraftable Potions Made Craftable.

I have a few ideas for how some uncraftable potions could be made craftable. My first idea was the potion of withering. This potion is only available in Bedrock Edition and is a rare chance of spawning in a witch hut cauldron. I think a new and obvious way it could be made is using a Wither Rose. Another uncraftable potion is the potion of luck which could be crafted using clovers that they could add in the new Lush Caves biome. Husks (which are kinda useless) could be made useful by being able to drop sandy rotten flesh or something similar which could be used to make a potion of blindness, backed up by the fact that sand can blind people.
