Do you need a standard printf, or an extensible printf?

In the latter case, do you need to extend the basic types? The modifiers?
The set of directives? Or do you also need to modify the implementation
of existing, standardized directives?

How does what you need compare with the register_printf_function /
parse_printf_format facility in glibc's public header file <printf.h> ?
