In general, the client now has an acknowledgment system that will cause block changes made by the client to be reverted correctly. Essentially: The client enters a "prediction" stage, where any block changes made will have its old blockstate captured (this is referred to as "server state"). If you update blocks during this stage, the client will update this captured server state as long as they're still currently predicting. After prediction is done (via an ack packet) all captured blockstates are reverted to their captured server state. This means that if the server actually updated a block and send a block update packet, it's correctly set, while if a block wasn't updated on the server but WAS updated on the client (server state wasn't updated), that change will be reverted. It should be noted that this system does not yet support block entities, so those still need to be resynced when needed. I discovered this when noticing that blocks broken outside of the player's valid interaction distance are still properly reverted, even though the server doesn't send any block updates, only an ack packet.
