uses the default namespace service account, and doesn't require additional RBAC permissions. - simplified label structure. Label change is not supported on upgrade. - for 'internal load balancer' you should deploy a separate gateway, in a different namespace. All ingress gateway have a "app:ingressgateway" label, used to identify it as an ingress, and an "istio: ingressgateway$SUFFIX" label of Gateway selection. The Gateways use "istio: ingressgateway$SUFFIX" selectors. # Multiple gateway versions...
