This is a very interesting point. Rollbacks are protected by consistency proofs and with inclusion proofs it's possible to detect such situation but it may require scanning over the transactions. immudb does not only provide access by key or key prefixes but it's also possible to fetch a particular tx by its unique identifier or scan over them.

For sure it's not the optimal solution, some ideas to cover this scenario were discussed but not yet fully defined.
