We don't have to fix this right away but it looks like builds might be broken in 1.16 because of go module changes.

(cd /home/hekumar/goal/src/github.com/golang/protobuf/ && go get -v -d $(go list -f '{{ .ImportPath }}' ./...)) &&
go build -o "protoc-gen-go" github.com/golang/protobuf/protoc-gen-go
no required module provides package github.com/golang/protobuf/protoc-gen-go: working directory is not part of a module
make[1]: *** [Makefile:66: protoc-gen-go] Error 1
