I believe Fedora follows the lead set by our own makefile and just
appends a "3" to the script name when there is also a Python 2
equivalent (thus ``pydoc3`` and ``pyvenv``). (I don't have any other
system provided Python 3 scripts on this machine, though)

It seems to me the existing recommendation to use ``#!/usr/bin/env
python`` instead of referencing a particular binary already covers the
general case. The challenge for the distros is that we want a solution
that *ignores* user level virtual environments.
I think the simplest thing to do is just append the "3" to the binary
name (as we do ourselves for pydoc) and then abide by the
recommendations in PEP 394 to reference the correct system executable.
