Allow more than one entry in spec.listeners and spec.listeners[].groups so a single EventGateway can advertise both an external and an in-cluster endpoint.

The new EventGateway API 11.8.x (events.ibm.com) is really well structured — modeling spec.listeners and spec.listeners[].groups as arrays with per-group endpoint + advertised-address config is exactly the flexibility we were hoping to leverage. While trying to use it, I have hit a wall where both fields appear to be hard-capped at one item. Adding a second entry to either is rejected by admission with:


The EventGateway "<name>" is invalid: spec.listeners: Too many: 2: must have at most 1 item


The EventGateway "<name>" is invalid: spec.listeners[0].groups: Too many: 2: must have at most 1 item


Since both are arrays, is the single-item cap intentional, and is multi-listener / multi-group support planned? I am trying a use case to advertise two endpoints from one gateway — an external host for remote consumers and an in-cluster host for co-located clients (Event Processing / Flink) — so the latter resolve the gateway natively instead of via /etc/hosts overrides.
