Buggering op[] would be the slowest possible way to get the NUL there. Some of us would have liked for string operations not to be as absolutely slow as can be achieved. Evidently that is a minority preference.
If you think anybody is complaining about the extra space for the NUL, what you are barking up is not even a tree.
