Which should be good. If the OPs arguments about how dangerous it is to empower and stuff a lot of functionality into pid 1, think of how running in kernel mode on a cpu gives you power when your code is in the kernel proper.
So moving functionality out of kernel mode and into user mode is great. The only steps after that are moving as much functionality as possible to the user, and then to nobody. We do trend towards minimum permissions for the sake of security for a reason.
Functionality is not being moved out of the kernel and into userspace. It's being moved out of legacy freedesktop.org components (hald, ConsoleKit, PolicyKit, etc.) and into PID 1. Where should it be moved to? /dev/null.
