What was done was certain parties made a one-sided announcement that ConsoleKit was deprecated without any discussion regarding the people who used it. Where was the call for new maintainers? Where was the call to see if the project still was viable? Re-reading the "discussion" thread still feels to all the world like a decision was made, regardless of the merits of keeping the project alive, because Lennart et al wanted to move everyone kicking and screaming to their new toy.

Furthermore, where is the GDM documentation on what it produces/consumes regarding dbus? Where's the API spec. I can find that it does use org.gnome.DisplayManager as its root, but what more from there? I have the feeling that few people are willing to help out here because Gnome feels about as transparent as a brick regarding these decisions.
