Agreed, but the real question is not that.

It is "who is responsible for restoring the interface state, and to
what extent"?

If you kick it out of the bus (cause a full hotunplug on rfkill block,
and a hotplug when rfkill unblocks), it is userspace.

But what if you do it halfway?   That's what is being asked here...
