You're extremely misguided.  This change, in fact, makes it ten times
harder for such applications to query such devices.

Because now the application has to decide whether it wants to support
EVERY EXISTING SYSTEM OUT THERE or not.  Hundreds of millions of Linux
systems do not provide this attribute.

Applications have to handle the case of not having the 'vlan' device
type available attribute essentially forever.

So providing it in new kernels provides zero value whatsoever.

I'm not applying this patch, sorry.
