following benefits and differences: * Designed with Helm best practices in mind (standardized values options, values schema, values are not all nested under `gateways.istio-ingressgateway.*`, release name and namespace taken into account, etc). * Utilizes Gateway injection, simplifying upgrades, allowing gateways to run in any namespace, and avoiding repeating config for sidecars and gateways. * Published to official Istio Helm repository. * Single chart for all gateways (Ingress, Egress, East West)....
