Well, apparently people want to use the BIOS to store the current rfkill
state -- this lets them do that. Now, I don't care if you implement it
or not, but now they could.

The point really is that when rfkilld starts up it has to impose a
policy, and the question is what that policy is and where it is stored,
if desired, across shutdowns.
