I found some time to dig into the source and found a few interesting 
points:
1. the dbus daemon name could be set to wathever else with 
-DDBUS_DAEMON_NAME=<dbus-daemon-name>, so this is feature isn't lost and 
everyone is happy :-)

2. There are use cases, in the kde context and may be others too, which 
require to have different dbus session buses running for a single user. 
There are several approaches available to reach this goal. Having a 
special dbus daemon executable name may be one of these approaches. It 
is worth to discuss the pro and cons of these approaches in a separate 
thread.

Because it seems there are no more issues with this patches I applied 
them to dbus git master branch.
