Why is no one talking about kernel assisted IPC bus?

Question

I've been looking at kd-bus and its later evolution bus1. Seems like both projects are stalled. Why are kernel developers not supportive of a proper messaging system through kernel itself? Or rather what is stopping them from accepting patches to it?bus1 -> https://bus1.org/Can someone help me understand?

Help me understand why Bus1 is a good idea? I'm not an expert, but it seems to me like D-bus accomplishes similar goals without any new mechanisms in the kernel.
