Well, for one because that's what I wanted to find out...

I used this language because I think you're not providing
the facts that would allow me to judge for myself whether
kdbus is a good idea. Those automotive applications you
were talking about, what was the OS they were ported from
and what was the messaging API they used?

As I said before, I'm seeing about a dozen D-Bus messages per minute,
nothing that would justify adding kdbus to the kernel for
performance reasons. Wrt security I'm also not aware of any
open issues with D-Bus. Thus I doubt normal users of D-Bus
would see any benefit from kdbus. I also think none of the
applications I can install from my distribution has any performance
issue with D-Bus.
And this is the point where I ask myself if I missed something.
Thanks,
Johannes
