Yes, that is one very important reason. Others are:

- right now if they want to use one widget, they need to do major changes in 
their code (switch to KApplication instead of QApplication, use KConfig, etc)

- every API you need to link to increases the risk of incompatibilities during 
your product cycle

- all of kdelibs is rather large, on the disk and in memory

- kde apps need infrastructure and if you start them on gnome or xfce they are 
pretty slow. Qt apps are faster.

- in order to be independent from the system most Qt developers copy over the 
code. All of kdelibs is a bit large to copy over. 
Dependency is here ment in terms of code stability (they don't want to be 
forced to port anything, over years), binary stability (API 
incompatibilites), availability (customers might run gnome or even xfce). 
Actually they even bring their own qt lib along.

It would be great to have:
- greater modularity
- garantied stability at least for some modules
