Could you think of using fmt.Errorf() instead of errors.Wrap() if you don't have any reason?

FYI the other errors package we often use in Kustomize is our own "sigs.k8s.io/kustomize/kyaml/errors", which provides errors.WrapPrefixf(err, msg, args...) for situations like these. We have plenty of fmt.Errorf usage as well though, so I don't feel strongly about this.
