I still see no reason why this should be put into CK. Wasn't CK about
tracking user sessions and seats? Imo this functionality doesn't
belong into CK.

Well, just check your fedora packages then [1]:
The PolicyKit package has a requires ConsoleKit.
And as the PK package ships libpolkit, ConsoleKit will have a requires
PolicyKit.

Such dependency loops are bad.

As I already said, HAL would be and is the correct place for this, imho.
