Despawn Block Into Air
Places a block item back into the world at an empty target location, doing its best to carry over the item's stored block data and tile-entity state (banners, skulls, container contents, sign text, spawners, and so on).
Faithfully carrying every possible block state is effectively impossible via the Bukkit API, so this covers the common cases and refuses items that are hazardous to place (explosives, gravity blocks, redstone, liquids, etc.).
Properties
Whether this strategy participates in bulk removal (removeFrom). Regression pin: DespawnIntoVoid applies to every block but removes nothing, so leaving it in the removal chain short-circuited /despi purge — no container was ever purged.
Functions

Whether this strategy is applicable to targetBlock.
Removes all of material from targetBlock (used by bulk purges).
Removes items matching material from targetBlock (used by bulk purges).
