If I understand this PR correctly, it tries to make empty master internal name allowed. That will break a few addons that must run before the kuberntes.default service exists. Since the manifests are rendered before LB creation, I am not sure how that will work.

Any example of such manifests?

Cilium always requires it. Calico when using BPF mode. Karpenter also references it, but not sure its strictly required anymore.

Easiest way to go about this would be to add a new entry in /etc/hosts on each node. Though, this won't work for LBs with stable DNS name only, like in AWS. At least I'm not sure that the internal IP is stable.

Looking good - one naming nit :-)
