-- With `--ts_proto_opt=noDefaultsForOptionals=true`, `undefined` primitive values will not be defaulted as per the protobuf spec. Additionally unlike the standard behavior, when a field is set to it's standard default value, it *will* be encoded allowing them to be sent over the wire and distinguished from undefined values. For example if a message does not set a boolean value, ordinarily this would be defaulted to `false` which is different to it being undefined.

 This option allows the library to act in a compatible way with the [Wire implementation](https://square.github.io/wire/) maintained and used by Square/Block. Note: this option should only be used in combination with other client/server code generated using Wire or ts-proto with this option enabled.
