Also, as I understand it, the Crossover airs ONLY on a Episode from "Supergirl", so it plays fully in the World of Supergirl and only Grant Gustin as the Flash appears. If this is true, the question should be "should The Flash be added to the Supergirl wiki?". The way I see it, this wiki shouldn't cover characters that aren't introduced in the Arrowverse. If they decide to pull a Constantine in the futue and have Kara show up on The Flash like you said, that would be a different story. Otherwise if it's just Barry showing up on her show, I don't see a reason to add her because of it. And if he starts mentioning her down the line, we can just create a page for Kara, but not bring her entire history here. There's already 5 shows the Arrowverse wiki is covering, bringing in Supergirl too would be an overkill imo.
