Between this link and the OP, we're seeing the first improvements to drop from Mark Shannon's Microsoft-funded full-time work on CPython optimization, alongside Eric Snow and Guido van Rossum:
https://www.theregister.com/2021/05/19/faster_python_mark_sh...
https://github.com/markshannon/faster-cpython/blob/master/pl... - indicates that this is step 2 of 4, where the forthcoming steps actually plan to introduce JIT compilation!
From the OP Changelog:
- bpo-44590: All necessary data for executing a Python function (local variables, stack, etc) is now kept in a per-thread stack. Frame objects are lazily allocated on demand. This increases performance by about 7% on the standard benchmark suite. Introspection and debugging are unaffected as frame objects are always available when needed. Patch by Mark Shannon.
And from the What's New:
- “Zero-cost” exceptions are implemented. The cost of try statements is almost eliminated when no exception is raised. (Contributed by Mark Shannon in bpo-40222.)
- Method calls with keywords are now faster due to bytecode changes which avoid creating bound method instances. Previously, this optimization was applied only to method calls with purely positional arguments. (Contributed by Ken Jin and Mark Shannon in bpo-26110, based on ideas implemented in PyPy.)
Really, really exciting beginnings. I can't wait to see what's next!
4 hours? Yeesh. Here's how to do it in 10 minutes.
Use pyenv to install any python version and pyenv-virtualenv to manage virutal environments.

The 2019 update https://github.com/python/peps/commit/ae932bd6fd2c493d7d64ce... allowed more flexibility, but the old handling is still entirely okay.
