For people like me who haven't heard of this feature: https://docs.cardano.org/projects/cardano-node/en/latest/sta... It's true that this prevents an attacker from using current keys to perform a long-range attack but old keys can still be used for attacks.

Afaik, long range attack is eliminated by bootstrapping from genesis, where the densest chain is selected.
