One kind of complex information. V4L with read instead of ioctl
would be horrible.

Nope. There's no sanity found if you need half a dozen
filesystem with strange failure modes if one happens to be mounted
on a different place or with strange permissions.
We need unification. There's nothing hotplug specific
about node<->device correspondence. It belongs
in driverfs. We need to get rid of special cases.
