IOW, is the added complexity of kdbus worth the result? I have stated my believe that current usage of D-Bus is not performance sensitive and the number of messages exchanged is low. I would love it if you would prove me wrong. Or if you could show that any D-Bus related bug in Gnome3 is fixed by kdbus. I would sooo love it if someone would finally post some data that proves kdbus is useful beyond systemd.
