Is there a reason the universal newline mode doesn't cover this case already? This module lets you explicitly create a text data file for any platform. The universal newline feature of python is for Python modules only, and lets you transparently import and exec Python source files with the different line ending formats. That is a different thing.

Not true. Python 2.3 added the "U" option for file opening to use universal newline support for any file you open. See http://www.python.org/doc/2.3/whatsnew/node7.html .
