It means that 3.x is always present (with 2.x an option) and Fedora's 
Python code works with the always-present version.

The actual proposal (FEP? ;-):
https://fedoraproject.org/wiki/Changes/Python_3_as_Default
'''
The main goal is switching to Python 3 as a default, in which state:

     DNF is the default package manager instead of Yum, which only works 
with Python 2
     Python 3 is the only Python implementation in the minimal buildroot
     Python 3 is the only Python implementation on the LiveCD
     Anaconda and all of its dependencies run on Python 3
     cloud-init and all of its dependencies run on Python 3
'''
...
"Upstream recommends that /usr/bin/python point to Python 2 runtime for 
the time being, so if we go with that, there shouldn't be any serious 
compatibility impact: "
