The underlying reason is that a malicious validator could take advantage of getting tombstoned
to avoid being slashed on the provider ([see comment](https://github.com/cosmos/interchain-security/pull/1232#issuecomment-1693127641)).

- Currently, the endpoint can only handle "equivocation" light client attacks. This is because the "lunatic" attacks require the endpoint to possess the ability to dissociate which header is conflicted or trusted upon receiving a misbehavior message. Without this information, it's not possible to define the Byzantine validators from the conflicting headers (see [comment](https://github.com/cosmos/interchain-security/pull/826#discussion_r1268668684)).

Without this information, it's not possible to extract the Byzantine validators from the conflicting headers (see [comment](https://github.com/cosmos/interchain-security/pull/826#discussion_r1268668684)). In addition, "amnesia" attacks are ignored, similar to CometBFT (see [ADR-056](https://github.com/cometbft/cometbft/blob/main/docs/architecture/tendermint-core/adr-056-light-client-amnesia-attacks.md#decision)).
