According to AIP-4235, auto-population of fields should be handled by the client library's RPC methods. If the generator is updated to support auto_populated_fields, this logic should ideally be placed within the generated RPC methods rather than the sample code. This keeps the samples clean and ensures the feature is available to all users of the library, not just those following the samples.
