Probably WEXT was a bad example. Why would somebody use private
interface for something where standard
one can be used? So people use WEXT private commands for something
that was not designed.
Then probably most of the "private" commands from WEXT were taken
into account during nl80211 design.
And this is great. However, apparently not everything was covered.

I disagree here, wireless community do have intensives to implement
standard interfaces. Simply because of different
and in most cases objective reasons, product demands are "quicker"
than open-source community response.
