Well, I don't think we want/need this.

See, Henrique says that the use case is Thinkpads which store the
previous state in the BIOS. But that matters to you only if you use a
mixture of operation systems, which we don't have to support.

On the other hand, people on machines that don't store the rfkill state
in the BIOS might care about having their machine boot up with the same
rfkill state(s) as they shut down with, so the sane thing to do would be
to have rfkilld store the state persistently, and then recover it at
boot. At which point the BIOS state becomes irrelevant and a detail we
actually end up not even _wanting_ to support because it means we need
to be aware of machine differences in userspace.
