That would be only true if you have multiple variables pointing to the same string without changing each instance. I don't believe that this the majority of code. Why would you use multiple variables then? After assigning the value of an AnsiString to another AnsiString variable I *always* modify it. And then the whole data gets copied too plus additional overhead like increasing the reference counter.
