Because there's nothing in D-Bus that is inherent Unix-only for the session 
bus. In fact, it can be built on top of any number of those IPC and just 
provide a marshalling and demarshalling mechanism.

What I don't think is a good use of developer time is to is adding hacks to 
make fork() possible, for example. It's never going to be fast and it's going 
to have weird problems. Better to know that one should use CreateProcessW. 
Ditto for trying to make it pretend that the OS has Unix sockets when it 
doesn't, or /dev nodes or useful signals.
