Because its not needed, compilation of the .cpp and _p.h files in the Qt
sources is under the control of Trolltech (for KDE its likewise under
control of the kde devs), so they (we) can make sure that the
buildsystem sets the needed include paths for using just #include
<QWidget>. 

The problem with installed/public header files is that you never know
who uses them with what buildsystem and wether or not he/his buildsystem
sets the needed additional include paths. So its important that when one
public header include's another one he does this in a way that
compilation of some third party sources only fails if there's no -I
switch for Qt at all.
