Manual talk:Hooks/PageContentSaveComplete

Is this hook still used? I did not find anything in WikiPage class from MediaWiki installations 1.8 nor 2.0. Also tried to find text "PageContentSaveComplete" from all of my MediaWiki 2.0 files and did not find anything. Hook ArticleSaveComplete states that it is deprecated and this hook should be used instead but if this hook has disappeared from MediaWiki installations, that text should be removed.
