Also looking at what already ships with Python.

idle, idle2, idle2.7
smtpd.py, smtpd2.py, smptd2.7.py
pydoc, pydoc2, pydoc2.7
2to3, 2to3-2, 2to3-2.7

This is also the convention anywhere someone does versioned scripts in a Python 
package in the ecosystem. PEP439 is there to streamline the process so that 
python dependencies are much easier to install and there's a smaller barrier to 
"entry" so that projects like Django can give simple instructions for 
dependencies instead of needing to opt not to have dependencies or have to give 
instructions on how to install the installer.
