Many Unix tools need Python, so Mac OS X (like Linux distros and FreeBSD)
will always need a system Python. Yes, it would be great if could be called
spython or something else than python. But the main problem is that it is
used by end-users as well, not just the operating system.
Anyone who use Python on OSX should install their own Python. The system
Python should be left alone as it is.
If the system Python needs updating, it is the responsibility of Apple to
distribute the upgrade. Nobody should attempt to use pip to update the
system Python. Who knows what side-effects it might have. Preferably pip
should have a check for it and bluntly refuse to do it.
