In a *vast* number of cases in existing code the size of the buffer is already fixed (e.g., it's existing code, it's a a fixed-size array in a struct, etc.). Having standard functions to address this common case is very useful.

In many cases dynamically-allocated strings are the better choice. In that case, strdup and asprintf are especially useful. But since fixed (preallocated) buffers and dynamically-allocated buffers are both in wide use, it's important to have useful functions for each case.
