There was a good Twitter thread today about finality, explaining that a protocol can't guarantee both immediate settlement and liveness. Yet Ethereum found a compromise by running two different confirmation rules at the same time after moving to proof of stake. When a significant part of the network disconnects, blocks will still be produced but finality will be postponed. (OK, I see something like that is also in the OBI proposal, but it's unclear to me what will happen when no quorum is reached at all.)

It's not reassuring to read that @blocktrades didn't study either Tendermint or Ethereum's Gasper. If Hive makes this change, the chain might become more likely to stop working during serious disruptions, like Solana.
