Also, gRPC's human readability challenges are overblown. A naked protocol buffer datagram, divorced from all context, is difficult to interpret. But gRPC isn't just protocol buffers.

There's a simple, universal two-step process to render it more-or-less a non-issue. First, enable the introspection API on all servers. This is another spot where I find gRPC beats Swagger at its own game: any server can be made self-describing, for free, with one line of code. Second, use tools that understand gRPC's introspection API. For example, grpcurl is a command-line tool that automatically translates protobuf messages to/from JSON.
