I've put the following APIs ``` def serialize_length_prefixed(message, output) -> None def parse_lengh_prefixed(message, input_bytes) -> message ``` into one of our projects' design doc. Will add the support once the...

MessageToJsonString is calling another function FieldMaskUtil::ToJsonString: https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/util/internal/protostream_objectsource.cc#L700

The error produced in descriptor.cc should also call AddError()/AddWarning() in CommandLineInterface: https://github.com/protocolbuffers/protobuf/blob/d0f91c863ae0fbb75b41460c8bbb786ade197a0f/src/google/protobuf/compiler/command_line_interface.cc#L289

We could add an option is json fotmat setting and a method public Settings WithPreserveFieldName(bool perserveFieldName) => new Settings(formatDefaultValues, TypeRegistry, FormatEnumsAsIntegers, perserveFieldName) https://github.com/protocolbuffers/protobuf/blob/master/csharp/src/Google.Protobuf/JsonFormatter.cs#L781 Are you happy to create a PR...

ToJsonName() is called in some helper APIs or generated code. Users can create their own JsonFormatter() with settings and then call formatter.Format(message). For example: https://github.com/protocolbuffers/protobuf/blob/master/csharp/src/Google.Protobuf.Test/JsonFormatterTest.cs#L90
