Official Istio client and/or model

Hello everyone,
Any plans for official Istio Client and/or Model for different languages (Java, Golang, Node, etc) in the works?

Right now, we are using Snowdrop’s istio-java-api, which is inspired by Fabric8’s kubernetes-model.
But it is not quite matching Istio’s releases schedule and some of the features like Sidecar are not added in the Client.

Any advice on the short term or near term plan is appreciated.

Thank you,
Bhaskar
