I agree, and would support moving it to kdebase/workspace.

I did not look at all the code paths fully, but from looking at 
qguiplatformplugin_kde.cpp, Qt makes sure it reads the "widgetStyle" config 
entry, falling back to KStyle::defaultStyle().

So what I would suggest is removing the style handling from KDE, and just use 
what Qt uses when it detects the KDE platform. This way KDE apps probably 
use GTK+ style when run from a GNOME session automatically. Not sure if 
that is the desired behavior.

Actually I thought that was your primary motivation ;)
