With NGINX Ingress deprecated in SMP (through 0.45.0, removed as supported at 0.46.0) and Envoy Gateway becoming the supported ingress via the Kubernetes Gateway API, teams that relied on per-team Ingress self-service lose a clean way to manage their own listeners and TLS certificates. The Gateway-native replacement for that pattern is the ListenerSet (XListenerSet, GEP-1713), and it is not currently supported by the SMP-bundled Gateway API stack. Current state On SMP 0.44.x, XListenerSet resources are not reconciled by the bundled ingress. In practice this means all listeners must be defined centrally on the Gateway resource, there is no delegated, namespace-scoped listener or TLS self-service, and teams remain subject to the Gateway's single-resource listener model and its historical 64-listener limit. Desired behavior SMP should allow ListenerSets to attach to Gateways managed by the bundled Envoy Gateway. Specifically: install the experimental-channel Gateway API CRDs (or provide a supported toggle to do so), reconcile XListenerSet such that resources reach Accepted/Programmed, expose the Gateway's allowedListeners namespace scoping through chart configuration, and let HTTPRoute reference listeners defined in attached ListenerSets. Because the resource is currently experimental upstream, feature-gating and a documented migration path to the standard ListenerSet (expected around Gateway API 1.5) would be appropriate. Use cases Platform teams running SMP who want application teams to self-serve their own hostnames, listeners, and TLS certificates on a shared Gateway without granting write access to the central Gateway resource. Multi-tenant clusters that need to distribute listener configuration across namespaces. Environments migrating from NGINX Ingress that need a Gateway-native equivalent of per-team ingress ownership. Deployments approaching or exceeding the 64-listener limit on a single Gateway. Business value Preserves the developer self-service and separation-of-concerns model that NGINX Ingress users depend on, so the forced migration to Envoy Gateway does not become a regression in team autonomy. Keeps infrastructure lean by supporting a shared Gateway rather than one Gateway (and its associated pods) per team, and reduces the risk that customers stall on the 0.46.0 upgrade because the ingress replacement cannot match their existing operational model.
