I think this depends on the use case. In the KDE on windows context - 
where this implementation came from - this "feature" has been used to 
run a release build for daily work and an independent debug build. KDE 
uses dbus-daemon to start further applications and kioslaves. If there 
would only one daemon, debug applications would start slaves from 
release builds and vice versus, depending on which daemon has been 
started first. This makes debugging much harder.
Because of this limitations the mentioned patch is used for KDE as default.

At least there are some specification extensions required before as 
David mentioned  - I will see if i can find some time in the next days.
