KDA failover strategy

Currently I am trying out a KDA + Flink setup and first thing that stops me a little bit is failover strategy. There is only one option for a failover: take savepoint -> destroy cluster -> start new cluster -> start job from savepoint, and this option ends up in few minutes downtime. I am aware that aws uses a bit different strategy for maintenance window where both clusters run at the same time and only job stop, start creates a downtime which is way shorter then the only available option. Does anyone know if this and when this second option will be available for cases like autoscale/ user maintenance/ etc.? And will it be compatible with custom autoscaling rules?
