Deletion of List of presidents of the United States by time in office

Comment: The fact that this list has been maintained and developed since 2004 and has been completely unchallenged until now gives me pause. On inauguration day, page views spiked to over 15,000,https://tools.wmflabs.org/pageviews/?project=en.wikipedia.org&platform=all-access&agent=user&range=latest-90&pages=List_of_presidents_of_the_United_States_by_time_in_office despite not even showing up in the first page of likely search results,https://www.google.com/search?q=president+of+the+united+states+wikipedia&ie=utf-8&oe=utf-8#safe=off&q=list+of+presidents+of+the+united+states+wikipedia,https://www.google.com/search?q=president+of+the+united+states+wikipedia&ie=utf-8&oe=utf-8 suggesting a lot of readers have found this separate list useful. And before  is raised, utility is key to determining whether to present lists on the same topic, organized in different formats and focusing on different facts; the nominator's argument is also essentially "it's not useful" and so they apparently agree that this is how we should analyze it. As pointed out above, the parent list of U.S. presidents does ''not'' present this information in this level of detail or in a manner that allows this ranking to be made easily. Given the attention that every aspect of the lives and service of U.S. presidents receives, length of service is hardly minor trivia
