Is your feature request related to a problem? Please describe
The Kubernetes project is looking to deprecate service.spec.externalIPs in k8s versions 1.36: kubernetes/enhancements#5707
They plan to feature gate externalIPs in k8s 1.40 and set the feature gate by default to false and then remove the feature entirely in version 1.43.
Describe the solution you'd like
kube-router currently supports service.spec.externalIPs so we should track this and look to deprecate and remove the feature as well in step with the upstream project and attempt to make our user's aware of the change.
Additional context
There is a draft of a blogpost here: https://github.com/adrianmoisey/website/blob/4b07942d78a2fdd086f93f5019c27a9b9b287cbf/content/en/blog/_posts/2026/2026-02-27-from-deprecation-of-service-externalips.md
