There isn't a "type all" rfkill class.  I have patches that export the
rfkill core global states, and one of the global states looks like an
"all switch" indeed (the Emergency Power Off global state).

I did try an "one rfkill class for each type, and a master rfkill
class" approach a few months ago, and it didn't fly.  I think I even
deleted it because it was too ugly to see the light of the day, or
something.

I will post what I have soon. I am not happy with it, but it might be
interesting to see if someone can come up with a better approach.
