> - there are multiple ways to retry - you can retry establishing the connection (e.g. say DNS resolution fails for a 30s window) _or_ you can retry establishing the stream

That's not how protobuf works? If a connection fails, you simply get an IO error instead of the next message. There is no machinery in gRPC that re-establishes connections.

You do need to handle timeouts and blocked connections, but that's a generic issue for any protocol.
