Cool software doesn't really happen without the ability for apps to communicate and read/write the state of the system and communicate with other user level components. I maintain that at the core of each of these new annoying packages is genuine user need, combined with poor execution and massive feature creep.
And the reason for this:
- execution is actually difficult
- requirements management is more difficult
I think most people on this list would agree that the core requirements could have been/should be solved without creating a configuration nightmare and/or discarding the UNIX paradigm. I maintain that this can be accomplished by isolating the actual requirements that are the reason polkit/dbus are shipped on every system, and separating them from the "other things that these things also do".
Mind you, I'm not sure /why/ I care, maybe it's because I like using Linux. :)

Yeah, dbus is extra sad considering that it came after all that. Message systems can be handy, but I agree: the implementation was (obviously?) not driven by requirements other than that of a developer going "wouldn't it be neat if I made a thing called dbus". My hypothesis is not "dbus is needed" but rather that "projects that use dbus are /sometimes/ driven by a genuine need that is not solved elsewhere". Hmm, perhaps scraping the dbus issue tracker for past feature requirements would confirm or disprove this..
I don't know, maybe it's not a solvable problem.
