No, this thing will not be in a released DeviceKit-power version. It's
the wrong thing to do, we all know it, we all agree it's bad, it's just
a matter of reverting the patch and moving on with our lives.

Yes, of course it will continue to be that way if we cave in and add an
useless and wrong interface to DeviceKit-power... in the name of porting
away from HAL without really know why we are doing that in the first
place.

Just stick with HAL till then and maybe focus your energy on solving the
problem in the right layer in the stack, e.g. X.org or whatever.
