I am looking for a way to represent various services running on various different meshes. So it will be helpful to know the service_name.namespace.cluster_name format and store that in a service registry.

Querying the domain from inside a pod as suggested in https://stackoverflow.com/questions/63732409/how-to-get-fqdn-dns-name-of-a-kubernetes-service is not an option here.

I was wondering if Istio maintains these names internally and exposes them through any APIs?
