Yeah, but they're all separate from any other preference pane. Everybody gets the same framework to create completely independent prefpanes, not hijack Apple's existing ones.
There are no hooks, for example, to modify the Displays prefpane; if Apple decides they want to update it, they're free to do so. On the other hand, a lot of graphics card vendors still needlessly add their own little tab to the display adaptor control panel and the desktop's context menu.
