True, but dbus in the past was mostly local to an user session.

dbus now is critical for most system machinery. It deserves, actually
no, it *needs* such a feature.

I understand all you said and I agree on the complexity, but I still see
it as a big issue for a component that sits side-by-side with init.

Somehow it didn't click for me before that message.

I realize debian has nothing to do with this, but still, as long as you
don't close the bug, I'm fine with wontfix...
