Doesn't kubectl rollout rollback already do this for deployments?

> Pinned deployments

Service meshes like Istio let you run mutiple versions of services that you can selectively route traffic to. You can sign up for it if you need it. What value do pinned deployments add over that?

I kind of get the problem parts of k8s networking. But other than that this seems like it makes already complicated kubernetes some more complicated for not so convincing reasons.
