   * <p>Public suffixes are a proper superset of {@linkplain #isRegistrySuffix() registry suffixes}.
   * The list of public suffixes additionally contains privately owned domain names under which
   * Internet users can register subdomains. An example of a public suffix that is not a registry
   * suffix is {@code blogspot.com}. Note that it is true that all public suffixes <i>have</i>

many as necessary with `addSubjectAlternativeName()`. This mechanism also supports a very limited
form of wildcards `*.example.com` where the `*` must be first and doesn't match nested subdomains.

By default certificates use fast and secure 256-bit ECDSA keys. For interoperability with very old
clients use `HeldCertificate.Builder.rsa2048()`.

- Allowed setting the `hostnameOverride` field in `PodSpec` to specify any RFC 1123 DNS subdomain as the pod's hostname. The `HostnameOverride` feature gate was introduced to control enablement of this functionality.
