| Story so far is described at https://github.com/kubernetes/community/blob/master/contributors/design-proposals/api-machinery/csi-client-structure-proposal.md | |
| - linked from https://github.com/kubernetes-client/community/blob/master/design-docs/clients-library-structure.md | |
| Would like libs to be more "fluent" - should join up with the native language features e.g. JavaDoc, per-platform | |
| OpenAPI (Swagger) has limitations which force ugly workarounds. | |
| - e.g. doesn't cover returning different types in response to a call e.g. a result or an error. | |
| - OpenAPI 3 fixes a number of these limitations | |
| Key difficulty is which verbs apply to which objects - Go doesn't natively have this concept. |
