> The current implementation of the new consumer discards the result of a 
> reconciliation if the member rejoined, based on a comparison of the member 
> epoch at the start and end of the reconciliation. If the epochs changed the 
> reconciliation is discarded. This is not right because the member epoch could 
> be incremented without an assignment change. This should be fixed to ensure 
> that the reconciliation is discarded if the member rejoined, probably based 
> on a flag that truly reflects that it went through a transition to joining.
