The earlier email was for hidden devices; the intent there is to hide
certain devices (e.g., switch control netdevs) from user dumps by default.

Adding an attribute at create time such as IFF_INVISIBLE for such
devices would be a follow on to this set - but leveraging the same
sysctl and sysfs bypasses.
