This was originally added in the early days of go.mod in order to ensure that the root k8s.io/kubernetes go.mod file reflected all the versions of dependencies we were using, and to ensure that go commands didn't spuriously increment these versions. With module pruning in go1.17+ and go defaulting to mod=readonly mode in go1.16+, this is no longer necessary.
