# Strip the HTTP-gateway and OpenAPI option annotations from api_v3's protos
# before generating Python from them, in the manner of internal/proto-gen/patch.sed.
#
# A gRPC client reads neither annotation, but protoc records the files defining
# them as dependencies, and the generated Python then imports their generated
# modules just to register the option extensions. gnostic publishes no Python
# distribution, so keeping the annotations would mean generating and committing
# gnostic's whole OpenAPI v3 model for options nobody reads.
#
# The `proto` target checks that nothing survived this patch, so a shape these
# expressions do not handle fails codegen instead of leaking into the output.

# The imports that only define option annotations.
