Currently mobile web UI offers a prominent entry on top of the page title:

This drives too much attention to one (quite arbitrary) user, which for the uninformed reader might look too close to the signatures of articles in the media, written by a single person. It also doesn't do much justice to the rest of contributors, and doesn't tell much about the history of the page. Instead, we could focus on the age of the page and the amount of volunteers that have worked on it, which does give a better impression of a) the collaborative nature of Wikipedia and wikis in general, and b) a sense of potential quality and maturity of the article.
Even if that string contains links to the page history and the user page, offering only a reference to the page history and a link is better. The last editor is not that relevant (and quite often it will be a bot), but the history gives you a quick glance to the fact that this page has been updated by several people at different points of time for reasons summarized in the description of each edit. From there you can click to user profile pages if you wish.
The history mobile page is ok already today, but could benefit from {T94297}.
