ExperimentalHostUserNamespaceDefaulting	feature_gate	list render never false

Enabling the defaulting user namespace to host. This is for containers that are using other host namespaces, host mounts, or containers that are privileged or using specific non-namespaced capabilities (e.g. MKNODE, SYS_MODULE etc.). This should only be enabled if user namespace remapping is enabled in the Docker daemon.
