Being in the right is very much a matter of taste. Python has always erred on the side o less optimization and more obvious behavior. So something that optimizes for performance while introducing subtle possibilities for bugs would likely be accepted by the C++, but not the Python commitee.

And I think that's ok. Python wants to be simple and straightforward and performance was never a goal.

If you need performance don't use Python, or write a python library in C/C++/Rust and do the heavy lifting there.
