What if we kept a legacy that went from the origin to, say
2.12.0 that was still Python 2 based?  And then had the new, Python 3-based start from 2.12.0?

This would provide a way for anybody who needed to get old source code up
to the current standard to do so, and would eliminate the burden of
converting the whole file to Python 3.
