Probably because I meant something different :-) You want the kernel built so that there are no (expanded) calls to trace_printf() but with support for modules that contain them. Then I can load a module into a distro kernel that contains trace_printf() calls for debug testing. Which is why I was suggesting a config option that only rand-config builds would ever set that would cause the calls to generate compile-time errors.
