I say its pointless because it doesn't contribute one bit for the manga's overall development due to being something so trivial, not to mmention the time it would take.
There're hundreds of match-ups possible, besides, we all know that feats come along with battles and only matter to determine who wins against who in vs sections (ex: By feats, Hiruzen gets destroyed by Gaara, but realistically he would never get stomped and would most likely be victorious due to how he was portrayed in the manga).
Not to mention the vs section would lose its meaning because everyone would follow the official list made by the author. Don't you think its much more fun to leave these subjects open for discussion and opinion? :>
