Some of us use python as a rapid prototyping language before writing "real" code in c or even (horrors) c++ for performance. This is what makes ctypes so popular, python becomes the glue between calls to well tested low level functionality. So the place of the std libraries in this paradigm is to replace the c-like functionality. In c mkdir does not return the directory name, so os.mkdir does not either, allowing translation of the final prototype to c where it becomes another well tested tool in the next evolution of the application. I can appreciate the need for higher level libraries in the std, but not at the expense of os, sys, and other 'dead' modules.
