It was so big not many people wanted to review it properly. There weren't many steps of implementation (essentially a single-patch dump) and it had some high level features which don't necessarily belong to the kernel. Developers of kdbus also brought up performance gains a few times, even though it's been pointed out the userland is not the problem. It was the actual implementation that was bad.

It's being reworked into bus1 which is a slim, generic bus implementation. Full dbus can be implemented over it, but it's not forced on people who just want a nice, light bus interface with some security guarantees.
