i don't think so..
the controls are just there with parent constraints and custom attributes
i think the regular way is to do the controls first, so then you can adjust the skeleton as you're painting weights instead of having to find the bone and twist and stuff

so....

if you have the control for the hand, and you've given it finger attributes that curl the fingers then after binding you can just adjust that control instead of finding the bone...

i think maybe it would have a clearer effect on a larger more complex skeleton...
