Minecraft 1.16.4

What would you like to have changed or added to Vampirism

Please add some way (in game) to stop the spread of a vampire forest, ie to turn it back into a normal biome (what it was before it became a vampire forest biome). The Vampire forest biome has spread into our player's bases. Players who do not want this are now out of luck. There should be an in game way to remove the vampire forest biome where we don't want it to be.

Possible solution: place an effigy and burn it, or use that thing that is in towns to initiate a raid that if beaten cleanses the biome.

Thank you.
