There's another benefit here that I haven't seen yet. Suddenly it becomes potentially reasonable to fully trust "clients". That enables much better anti-latency

There's another benefit here that I haven't seen yet. Suddenly it becomes potentially reasonable to fully trust "clients". That enables much better anti-latency schemes which, combined with the clients probably being on the same low latency cloud network as each other, could potentially produce some really fantastic results. But you'd probably have to design the game engine around it.
