[Baypiggies] Whither `python` OR `python2` and `python3`?

[Shannon -jj Behrens]

It doesn't make sense for /usr/bin/python to ever move from Python 2 to
Python 3 because that would be too incompatible of a change. Nor do we
always want to keep dragging Python 2 around. macOS removed Python
entirely. Hence, I think not having a /usr/bin/python that points to Python
2 (or Python 3) makes sense to me.

If they made it really easy to have multiple Python versions installed
without adding other package repos, that'd be great. I haven't tried it
lately (so what I'm saying could be wrong), but the last time I did, it
wasn't easy. I usually end up having to use pyenv or installing some other
package repo.
