Probably because QPainter is dog slow.

Also, I don't think you should be against OGL wallpapers, considering
some really sweet/impressive things could be done with them which
could really make KDE stand out. e.g. a wallpaper playing a moving OGL
scene, movies, virus wallpaper (which is currently a large CPU drain,
and has no HW accel afik). Take Win 7 for instance, how they have
"Dreamscene™" or whatever.

Having features like this is similar to having neat and incredibly
useless OGL window animations (e.g. cube), ergo...everybody wants
them, haha ;)
