OK, to rephrase, that means we have two switches ("hard" and "soft") to
power down the hardware (both need to be unblocked for usage).

In theory, that is exactly what the soft/hard block state of rfkill are
for in the kernel. But for that to work properly, you will need to be
able to sense the hardware switch state independently.
