Of course not from a single state: it just tells you about the
current keys, not about their history.
If you are using a storage with history (e.g. "FileStorage"),
then the history can allow you to retrieve earlier states.
Comparing the current and some earlier state allows you to
determine additions/deletions (to some extend).
