a technology is also created if we have an RFKILL switch for that technology, but no device. This can happen with Bluetooth for example. You see a platform RFKILL switch, but the device will only appear later when RFKILL is unblocked. > > 2.

I think BLOCKED and OFFLINE should be the same. I don't think we need BLOCKED at all.
