It just happens though that the two options are related to regulatory --
maybe then this should have a different name? I still don't see the
need. What would you put under it in brcm[sf]mac? I certainly wouldn't
see any reason to put anything under it in our driver since it's much
simpler to .

Also, the argument about distros doesn't really work that way, if there
are users interested in something then the distros will certainly enable
this (CFG80211_EXPERT) option to get something hidden behind it.
