Greg, from my spell in IVI, I too have to say your faith in the wisdom of IVI developers' choices is touching. I think D-Bus was in the main picked because it had some nice features, but then people realized it had no bandwidth, and the solution has been "make D-Bus faster", rather than "maybe we should explore other (mixed model) solutions". This isn't to say that I'm against adding kdbus, but I don't think there's much strength to the argument you make above.
