UIAlertAction considered longwinded

Even for Cocoa, adding actions to a UIAlertController is tediously verbose.

[alertController addAction:[UIAlertAction actionWithTitle:title
                                                    style:UIAlertActionStyleDefault
                                                  handler:^(UIAlertAction *action) {
  doSomething();
}]];

The string "action" appears six times in the method call. There are only three kinds of actions. Wouldn't this be clearer?

[alertController addDefaultActionWithTitle:title handler:^(UIAlertAction *action) {
  doSomething();
}];

Yes it would.
