Coming from the Ruby and Node eco-systems I know what you mean, but I've also found it to be not that bad to roll my own depending on the complexity of the service. In some cases I'm finding I like it better that way because it's less "magic." For example, I can open the module anytime and see how the HTTP request is being made to the K8s API.

Definitely not for everyone or everything, just thought I'd share the thought.
