Dear Bruce, the main problem with this is that if you want to provide a consistent interface to the upper-level userland and to include support for fancy concepts like "session" and "seat", as systemd aspires to, you must have control on all the low-level userland. There is no other way. Your interface cannot remain consistent if a random developer can change a functionality in consolekit without letting you know. This is why systemd "had" to incorporate the functionalities of a few dozens different daemons and projects down there, including logging, hardware detection, authentication, network connection, and a myriad more. Like it or not (and I pretty much dislike it), the way systemd went down incorporating almost everything is a "natural" way to try to tackle complexity, i.e., by centralising things in the hands of a minimal number of actors and creating a whole lot of interdependencies. I personally think this does not work in the long run, and I find it clashing with the most basic KISS principle. This is enough for me to firmly refuse similar attempts.
