As I said, we have been using NSLog and StringWithFormat: for many years, and I think most people don't have any difficulty understanding how a variadic function work.
If we removed this feature, existing APIs would break. I don't think we should be afraid of breaking old code. However, no one convinced me that variadic functions are as bad as ++ operators that worth removing it.

Whereas, if you remove the feature, those people of the opinion “it makes code a tiny bit more readable” have nowhere to go.
