They began work on a logind compatibility layer over ConsoleKit2, they're writing a NetworkManager alternative, they directly influenced and are supporting a udev alternative called vdev (which also has libudev compatibility), and a host of other things.
For a rage-fork, it's pretty impressive. They're changing a lot. It's easier to just astroturf in the corner, though, I suppose.
Have you a notion as to why they're using vdev rather than eudev? What appears to be the vdev introductory blog post makes no mention of eudev.
And that stripping will be more complicated moving forward, as i recall a recent systemd release moved various bits from udev to a new systemd lib. Leaving the udev interfaces as stubs to be removed at some undetermined future date.
Then again systemd gobbled other critical components such as udev, there's also gnome that made it a strict requirement, like a cancer it grows and takes over other components.
