As a frequent user of ingress, I agree that portability isn't useful in practice and that requirement is a hindrance on ingress evolution. A lot of work has been put into CRDs, yet parts of the community push for a "portable" ingress. With all the one-off features/settings, users will inevitably make substantial changes to their ingress object - might as well use CRDs with clear specs. The alternative is annotation hell or associated configmaps.

I've heard some say they want to be able to list out all external addresses exposed from the cluster, but that can be solved with a new resource more akin to endpoints.
