Python community request to postpone breaking changes in Python 3.9 to 3.10

> So in 3.8, they kept code that had deprecation warnings so that they could be compatible with 2.7. They'd like to now drop that code and be 3.9-only compatible, but they don't have enough time to do that because they couldn't start that work as long as they were supporting 2.7.

> So the dilemma is essentially how hard we push users to abandon 2.7 -- how much tax we incur on them for keeping its support.

Its fascinating to see how the details of Python 2.7 EOL are still being figured out, and nuisance of the decision are still being debated.
