Wow, great work! Thanks for the amount of comments and the big test set, it was very pleasant to read!
I have some comments and suggestions below, please address them before merging.
One big question that I have, is using C lib instead of C++ one - how hard it would be for use to support gRPC features as Auth, interceptors, etc? It is available is C API?
