The problem is that WE over netlink is basically using netlink to
transfer the same binary blobs as the WE ioctls, rather than using
properly structured netlink messages.

The point is that if WE over netlink is used by applications, then the
kernel must maintain that ABI (of WE over netlink) forever.
