Stale endpoints on scale to zero #14336
Scale deployment to 5 replicas, see all 5 in
Scale deployment to 0 replicas, endpoints still remain in

This is not very critical, because if you have 0 endpoints you aren't going to have any successful requests anyways
If a,b become unhealthy due to readiness-probe failure, the cluster will have only 1 endpoint c. So far so good.
But if c also become unhealthy, we expect the cluster become empty, however, the unhealthy endpoint c seems always there.
