I disagree. If someone else wants to continue to develop Python 2 outside the Python foundation and formalised development community, then that is their prerogative, but Python has the right to decide what is and is not Python.

Dilution of what is commonly accepted to be Python would not be a good thing, and would further add to confusion.

I know that platform upgrades are painful, but we need to move with the times or we'll all be mired in technical debt and old technology.
