Added two minor comments. Also noticed that we still have a bunch of main.go files:

find . -name "main.go"                                                                                                                                                      
./cmd/argocd-server/main.go
./cmd/argocd-util/main.go
./cmd/argocd/main.go
./cmd/argocd-repo-server/main.go
./cmd/argocd-application-controller/main.go
./cmd/main.go

Can you please delete all except ./cmd/main.go ?
