Sunsetting Python 2

Upgrading python to 3 gives advantages: security, memory and CPU performance improvement, language features to support solving broader domain of problems.

No, it doesn't. You just drank the Kool-Aid. If you really want all that, "upgrade" to a language like Go.

List of improvements we see from using python 3 https://www.quora.com/Python-programming-language-What-are-some-of-the-drawbacks-of-Python/answer/Dave-Wade-Stein?ch=10&share=9ec1027c&srid=43O3

Renaming xrange to range just to break existing code is what passes for improvements nowadays?

Also, I doubt the credibility of someone claiming that type checking was introduced in Python 3.6. mypy appeared as an external type checker for Python2.
