   The loadbalancing algorithm was/is the same in both loadbalancers. The "old" one used asynchronous state-sharing while the new one uses sharding.
   
   The "old" loadbalancer was deprecated and removed because under load the state-sharing was far too slow and caused loadbalancing issues. Algorithm wise, both are the same.
   
   Towards the algorithm: It is an algorithm that gives you statistical probability on warm starts. Of course we want to "fully use warm containers", that requires extending the state in the controllers + removing all scheduling logic from the invokers. We're not there yet.
