Should SDK refresh address cache on an interval even when there are 4 replicas present?

For this particular case, the customer might have so many client instances which were idle for quite a while. The clients held the stale address cache. Later when the clients tried to send the requests to the backend, it is possible that each client suffered the high latency once before the offline replica throws ConnectTimeoutException

Question for SDK team, can we have an infrequent timer to refresh the address cache for the case when there are already 4 replicas?
