I've converted this PR into a draft as we need to be more considerate on this one. We probably also need to provide correct support for multiple URLs on the Gateway side.

For completeness - setting allowed origins to * is something that Gateway allows, but I do not think we should allow via the chart as it is insecure. Instead, Gateway should support defining multiple hostnames

Closing this PR as we decided it would be better to be a feature in Gateway instead of here.
