gVisor has historically silently failed for unknown protocol options. In the interest of not breaking existing users, we want to keep that behavior while adding metrics to track how much this behavior is used in practice. Eventually we'd like gVisor's behavior to be in line with Linux's. PiperOrigin-RevId: 748459211
