As of right now we don't plan on offering this feature. There is the potential for duping items.

We might not get around doing this at some point. If we despawn the entity, keep the reference to it, serialize it a few ticks after we have successfully despawned it and then transfer it, what could go wrong?

If our history with entities that can have an inventory is correct, everything.
