Do not use node's local storage if it is clear that an object will be
removed anyway as a redundant. It requires moving the changing local storage
logic from the validation step to the local target implementation.
It allows performing any relations checks (e.g. object locking) only if a
node is considered as a valid container member and is expected to store
(stored previously) all the helper objects (e.g. `LOCK`, `TOMBSTONE`, etc).
