Sickened Mob Farm

Much like how the Wither's Storm's presence can corrupt mobs, Mob Spawners should be corrupted to spawn sickened mobs after being nearby it for a certain amount of time (Zombie Spawner becomes a Sickened Zombie Spawner for example.) Given that the WS has a Command Block inside itself, it wouldn't be too farfetched to be able to corrupt certain entities like mob spawners. (I'm unsure if the mob spawner is magic or machine)

This would provide an alternate way to grind for sickened mob loot in addition to the Withered Beacon.

This could actually be a good way to solve the golden apple stew problem.

On top of that, same may go for Trial Spawners (if next update is 1.21)
