I'd argue in general that outside of python, there's not really much of a focus from google itself. They are largely leaving other language bindings to other people (see what's currently going on with tensorflow 2.0).

Their focus is more on the c bindings and allowing other people to build what they want on top of that.

Other language bindings aren't generally going to be used for anything more than inference. First class actual data science work isn't going to happen in other languages anytime soon (at least outside of julia and R which are at least trying to compete in this niche).
