It's fairly common to word things that way in Wikipedia articles, though of course not for every citation. It's a judgment call whether it should be or not, since adding a qualifier in-text more strongly contextualizes the claim as being from the source, rather than in "Wikipedia's voice". For example, I recently wrote an article about an ancient Roman politician. A number of sentences are in the form "[Scholar A] argues that the person did X [cite]" rather than "The person did X [cite]". I'll use the second form for uncontroversial facts, but the first form when it's more like a proposal from a particular scholar which isn't necessarily an accepted consensus viewpoint.
