Previously, ValidateNodeSelector did not check that labels are valid. Now it does for resource.k8s.io, regardless whether an object already was created with invalid labels in an earlier Kubernetes release. Theoretically this is a breaking change and could cause problems during an upgrade, but that is highly unlikely in practice. In contrast to node affinity, DRA does not ignore parse errors (= uses NewNodeSelector, not NewLazyErrorNodeSelector), so invalid labels would have been found instead of being silently ignored. Even if some object has invalid labels, this only affects an alpha -> beta upgrade which isn't guaranteed to work seamlessly.
