They are effectively both dead or moribund. Jython has had a py3 experimental branch for ages but the entire project is basically starved of money and effort.

To be honest, the whole “Python on other runtimes” movement, as a concept, is more or less over. It’s just too much effort for too little reward, now that CPython has good libraries for pretty much anything you can think of.

Does that view include PyPy? I'm not deep into Python (aside from the Monty kind) but it seems to be maintained and makes performance claims.

PyPy is a python-focused project that builds a python-focused runtime. My comment was more about projects trying to retrofit Python on top of runtimes that were built for very different languages, typically because of some constraint that has now disappeared.

The GIL constraint has not.

[toyg]

If the GIL is so important to you that you're willing to suffer the pain of running on another VM with a much-reduced ecosystem, while at the same time having requirements so complex that PyPy cannot meet them, maybe Python is just not the right tool for the project.

Moved the goalposts.

I am sorry that you see statements of fact and acceptance of reality as an adversarial debate.
