I actually think we need to scale things back a notch wrt pushing
wireless.git bits to users of released distros.  The recent disaster
in wireless caused a shitstorm in bugzilla that we never even saw
in rawhide.  A clear sign that we're pushing things too fast to users.

It's great that we're getting this stuff tested, but at the same time,
it doesn't give a great impression, and makes users reluctant to always
apply the latest updates if the last time around they have to deal with
this kind of fallout.
