Indeed, the uu module is a short Python wrapper around binascii. It's only 206 lines, much of which is comments or docstrings: https://github.com/python/cpython/blob/a5b7678a67ac99edd50822827b772e7d9afc8e64/Lib/uu.py https://github.com/python/cpython/blob/a5b7678a67ac99edd5082... It has three functions: one to encode, one to decode, and one to show usage information and handle arguments. It's only had 3 commits since 2010. There just isn't much to maintain.
