Well if the pages aren't cached the notice isn't shown.

Most of those pages support other system messages. For example Special:Wantedpages also displays mediawiki:wantedpages-summary. The majority of special pages follow that pattern.

You can discover system message usage using the uselang=qqx trick (Go to urls that look like http://www.knowpedia.in/wiki/index.php/Spezial:Gew%C3%BCnschte_Seiten?uselang=qqx and MW will show you what messages are available [more or less]).
