https://github.com/hyperledger/fabric-protos-go-apiv2/blob/main/google/rpc/status.pb.go needed?

I've noticed https://github.com/hyperledger/fabric-protos-go-apiv2/blob/main/google/rpc/status.pb.go is new relative to the prior fabric-protos-go. Does anybody know the origin of this new message? Is it used anywhere?

Errors from the Gateway service get returned to the client as gRPC status errors with attached error details, following the Google richer error model for gRPC. See the gateway proto definition.

Mostly this is hidden by the gRPC API but there are a few places where it leaks out and we need to interact with the Status proto directly in the Gateway client code, either for testing purposes or to extract information into a more consumable form for users of the client API:

• Generating server response message in Java unit tests
• Unpacking error responses to an object representation in Node implementation
