Manual talk:$wgTitle

Sometimes it really is hard (if not impossible) to avoid using $wgTitle, because a lot of hooks don't provide an $article, $title, $revision, etc. Does anyone know of an extension(s) that changes the value of $wgTitle? If so, it might be good to create a category, Category:Extensions that change the value of $wgTitle, so that site owners know to avoid mixing those extensions with extensions that rely on $wgTitle not being changed.
