Hello! 1) I think that rebalanceDelay is an outdated option, now that we have baseline topology and baseline auto-adjust. Just set baseline auto-adjust to the value of rebalance delay and you will be much better off.
2) I'm not sure it was, but definitely not anymore. 3) I don't think so, you will have to recreate.
