Which is how it should be till the end of times.
Unfortunately, ArchLinux decided otherwise, which has caused quite a bit
of grief in the office, where a coworker uses it.
We thought we could get around the problem by specifying
 #!/usr/bin/env python2
in all of our scripts, but, regrettably,
 (1) Not all of our python tools are written by us
 (2) MacOS doesn't have a python2 alias for Python2
> Typing "python" or "python xyz.py" at the shell will also use python2.
> Python3 will have really taken over when it's the other way around and
> python2 is the optional install.

I disagree. It is enough for the oldest supported Linux and MacOS distro
to support Python3 out of the box.
