Chapter 8 keyvalue.proto DeleteRequest returns PutResponse

Line 43 in 8aafc16

rpc Delete(DeleteRequest) returns (PutResponse);

Shouldn't the DeleteRequest return a DeleteResponse? Seems correct in the book, or is it ok either way because both responses are an empty struct?

However, when looking at the generated keyvalue_grpc.pb.gofile on page 236 Delete does return a *PutResponse, aligned with the repo., so is this a typo in the book?

It seems to me that there is a typo in two places.
