Your response is a massive mischaractarization of the status of kubernetes. It's FUD.
1. Service discovery.
When people say service discovery, they usually mean the ability for a given application to discover other copies of itself and other services & applications within a cluster.
Kubernetes has this down. It has it down better than almost any other system.
The "Service" object in the API can be used for in-cluster service discovery, the service-account tokens can be used as a powerful means of introspection and discovery, etc.
The things you link to are neither relevant. The first is about making api-servers more HA and federation better I think (unrelated to user's services) and the second is a proposal which is implemented, done, and didn't really catch on tbh. It's implemented because, well, it didn't propose any code changes on top of all the features services provide now, just some standard metadata users can opt in to adding if they want that sorta thing.
2. Secret storage
The Secret api object works great. It's done. Adding vualt support is an ongoing feature, but it is in no way a bug, it's just a feature request/enhancement. It's good that kubernetes is evolving, but that doesn't mean that the feature isn't already working.
Configuration scheme
You linked the same issue as before, typo I assume. I have no clue what you're talking about though. ConfigMaps are basically done. Downward API is nice. No clue what you think isn't "fixed".
Please quit it with your FUD. You obviously have no clue wtf you're talking about
