I read PEP 394 (https://www.python.org/dev/peps/pep-0394) differently. It states

> The more general python command should be installed whenever any version of Python 2 is installed and should invoke the same version of Python as the python2 command

Rather than permitting python to refer to python2 during a transition period, that is the recommendation. They later state

> It is anticipated that there will eventually come a time where the third party ecosystem surrounding Python 3 is sufficiently mature for this recommendation to be updated to suggest that the python symlink refer to python3 rather than python2.
