No, but for a few reasons.

It is easy to hide devices in a dump:

https://github.com/dsahern/linux/commit/48a80a00eac284e58bae04af10a5a932dd7aee00


But I think those devices should also not exist in sysfs or procfs which
overlaps what I would like to see for lightweight netdevices:

https://github.com/dsahern/linux/commit/70574be699cf252e77f71e3df11192438689f976


and to be complete, hidden devices should not be allowed to have a
network address or transmit packets which is the L2 only intent from
Florian:
