# Primary purpose of this config is to replace ::util::Status with our custom
# light implementation ::tflite::gpu::StatusLite to reduce binary size.  Besides
# that, certain features that were hard to communicate without full open source
# were hidden away too such as compiled models, serialization, and metadata.
# While the latter will be fully available with the open source release, the
# former will have to stay until absl::Status is released.
