Go1.16's go vet warns this reflect.SliceHeader usage. See also https://golang.org/pkg/unsafe/

In general, reflect.SliceHeader and reflect.StringHeader should be used only as reflect.SliceHeader and reflect.StringHeader pointing at actual slices or strings, never as plain structs. A program should not declare or allocate variables of these struct types.
