Yes, we agree. :-)

I guess what most people use it for is turning down the volume of Adobe Flash, 
which doesn't support the dbus interface. Yet. :-P
But degrading gracefully from the PulseAudio per-app mixing to the Phonon one 
would be neat (or from the OSSv4 one, if/when someone does that), I think.
Is this kind of runtime changing of backends doable in KMix?
