Remember, the salient point is ensuring that WE<=20 continues to work as 
expecting, without any modification.  If that means a compromise in 
supported SSID values, so be it.  Just like older versions of stat(2) 
syscall, you are stuck with the old interface, warts included.

But if we can support both styles... great!  I'm all for it.  Just 
noting priorities.  Warts and limitations are inevitable with older 
interfaces.
