unnecessary. so many better items, and if you build right she wont ever run out of mana anyway and if you do just pop a blue.
Why do you think people build Lich and Luden's on Sona, but not D. Cap? Because playing into her scalings is stupid. They're all miserably low (None higher than 50%), but Luden's and Lich have their own bases and scalings that add free damage for her, and all she has to do is land Q, unlike others who can get more damage out, but can't do it as easily.
So in Athene's case, it's the ease of application of using a Q to get like 200 bonus healing, then quickly slamming out W to get 400 health and a shield onto someone rather than 200. You're literally increasing the single-target value of Sona's W by 50% with this one item each time you use Q, then use W (for anyone but you, anyway).
Besides, it's not like I'm building Ardent Censor on her.
