There are a handful of files containing a list of variables that is intended to be kept sorted, including at least

• pkg/features/kube_features.go (❌)
• pkg/features/versioned_kube_features.go (❌)
• staging/src/k8s.io/client-go/features/known_features.go
• staging/src/k8s.io/apiserver/pkg/features/kube_features.go (❌)
• staging/src/k8s.io/controller-manager/pkg/features/kube_features.go
• staging/src/k8s.io/apiextensions-apiserver/pkg/features/kube_features.go
• test/e2e/feature/feature.go (❌)
• test/e2e/environment/environment.go

The ones marked ❌ are currently not sorted in master (and the other ones only have 1 or 2 elements in them and would presumably be unsorted if they were longer).

Someone should write a linter that checks this.
