Wandering trader sells bucket of sulfur cube

I would like this addition for wandering traders, as it would be quite simple and would greatly help newcomers to show that they have the resource in the game, and it would give players in skyblock or superflat worlds a chance to use this new feature. I believe it won't affect exploration in search of the biome, as the chance of getting a Bucket of Sulfur Cube or any other trade is below 10%.
