the better question is why it cannot be in parallel? Why would the other 
stages have a problem with no window manager being around?

Feel free to check the source base for where KWin talks to other components. 
I'm not of any direct usage, but we are using frameworks (e.g. lots of 
KServiceTypeTrader, KPluginTrader) and we have plugins which might do it (e.g. 
Oxygen window decoration might do things, etc. etc.).
