According to the [Minecraft Gamepedia page for Swamp Huts](https://minecraft.gamepedia.com/Swamp_hut "Minecraft Wiki page for Swamp Huts"), potions of decay have a "rare chance" of being spawned inside cauldrons in swamp huts, but the exact chances as not specified. I have checked over 50 swamp huts using [the Witch Hut finder in Chunkbase.com](https://www.chunkbase.com/apps/witch-hut-finder) on my survival world, and none of them had a potion of decay. 

In the history section of the wikia page it is said that in Pocket edition Alpha 0.16.0 Build one, potions of decay were added to the loot table, but the [page for the build itself](https://minecraft.gamepedia.com/Pocket_Edition_Alpha_0.16.0_build_1) did not include any information whatsoever on this matter.

So my question is, are potions of decay actually part of the loot table of potions that generate in swamp huts?
