As a courtesy, we should add a list of links to few pages in the MediaWiki namespace to e.g. MediaWiki:mainpagedocfooter, or as a new independent message, which an installations are likely to adopt to their own needs, such as MediaWiki:sidebar, and few others.
Let us also provide the new wiki owners a list of messages in the MediaWiki namespace which they should check in order to see that they are grammatically correct for their wikis {{SITENAME}}. Since {{SITENAME}} does not come with {{GRAMMAR}} by default, it largely depends on chance for many languages whether or not standard messages using it are gramatically correct.
