The vet-proto step fails in the checks with the proposed changes, what needs to change to allow for them to work with the generated files now containing the additional comment(s)?

Changes to the code generator will require that you re-run ./regenerate.sh from the root of the repo. That will also give us a preview of how the generated code looks.

I ran regenerate.sh but it doesn't run in a container, so it uses my system's protoc version instead of 3.14.0 that's in the existing files.

Would you mind downloading that version and making sure it gets run instead?

      PROTOBUF_VERSION=3.14.0
      PROTOC_FILENAME=protoc-${PROTOBUF_VERSION}-linux-x86_64.zip
      pushd /home/travis
      wget https://github.com/google/protobuf/releases/download/v${PROTOBUF_VERSION}/${PROTOC_FILENAME}

I don't know why those tests are failing, they seem unrelated to my changes as far as I can tell.

LGTM. Can merge once the nits are taken care of.

I'm not sure what else needs to be done?

[easwars]

Thank you for the PR !!

Now that this is fixed, is there going to be a new version tag for protoc-gen-go-grpc?

Yes, we will get that out soonish. Filed #6060 to track.

Hi @andremarianiello, you should find the fix included in our latest release of proto-gen-go-gRPC. Please feel free to reach out if there are any concerns.
