Why would a Wikipedia article require a date? Someone else just posted a Wikipedia article about an ancient Aztec city but I think it would be kind of ridiculous for the title to include (1325).
Point of adding the date to the title is to provide context where relevant as it relates to the present. Generally speaking, goal of HN is to cover substantial new information on a topic - not repeatedly rehash topics. As is, this Wikipedia is not a good fit for HN unless their’s specific substantial new information and the source of that information would be the best URL, not the Wikipedia page.
