If you look at the reasons for this it seems like a good decision: https://discuss.python.org/t/pep-836-jit-go-brrr-the-path-to...

There are already many way of addressing Python performance (leaving aside whether Python is a good choice if performance matters) such as Cython, Numba, Pypy and C extensions.

The problem with PyPy, which I'm a huge fan of BTW, is it's on life-support. The only reason the past couple major versions were released was due to a few small companies or individuals directly implementing the updates themselves. That's my understanding at least. It's disheartening because I've been primarily using PyPy for 5 years, advocated for it, and was looking into contributing more to it before finding out about its state.

And all of them are lacking in different ways, we ALSO, want faster pure Python.
