Definitely in the "because it is there" camp of routes, because a full rest preceeds the extension. The route was partly motivated by the Goats and Cattle name, which begged to be reversed.
After your choice of the two uproutes, you're on a ledge with a full rest. So Goats-and-Cattle is the better extension, but much harder without any rest going into the traverse. This is a cool extension if there's no way to you do Goats-and-Cattle, or if you've done it and feel like seeing what it's like to traverse it backwards.
