For the thousandth time:

All of those scripts and other users of this new facility will
need to have backup code to detect vlan devices when this
sysfs thing is not present.

They are already to determine this information already, and
they alreayd have to be ugly to handle EVERY EXISTING KERNEL
ON THE PLANET.

So the effective value is zero.
