It is unfortunately indeed. I think iwconfig and friends will never go 
away although iw is a better alternative, simply because people don't 
like to change their home-made scripts/tools. WIRELESS_EXT actually is 
largely, but not entirely, gone in upstream drivers and what we are 
talking about here is CFG80211_WEXT which allows WEXT userspace to 
interact with cfg80211-based drivers through a compatibility layer.
