Composition is simply not an option. And for some users, it never will.

Plasma is an essential part of KDE. Now you define that non-composition users 
are not the primary target of KDE? Why is about 50% of all users not the 
primary target?

As an intelligent human, you should be able to compromise. You have learnt 
from the mistakes done in kicker, and you don't have to repeat them. But still 
you cannot deny some essential features, eg. a nice looking Desktop, from such 
a large number of people. I agree that this is very close to the border, but 
you can also say "until here and no step further".

The color needs to find its way from the desktop shell into krunner, kwin, 
etc., so how should that happen without a configuration file?

Right now I would even be happy if it did not have any configuration UI at
