Many of these properties no longer require the prefix for most browsers. For these properties having the webkit prefix only, without the non-prefix property to cascade to, is a problem. I recall many demos, examples, and live sites not displaying as expected in Firefox because the developer decided to use only the webkit prefix. If the webkit team were to start removing the webkit prefixed properties then those sites would have even more broken views.
