I always see Safari as a small GUI around vanilla WebKit -- i.e. Safari basically is WebKit. (Chrome on the other side has pushed it much further and WebKit seems to be only a part of it.)
From the history of WebKit, I also got the feeling that Apple did one of the most important work to modernize it to compete with IE, Firefox, Opera at the time it was released. Afaik, KHTML was not really as far.
Under this view, I don't really see your point. This work by Apple (WebKit/Safari) and by KDE is now part/base of one of the most important browsers, Chrome.
