"Thoughts" is such a nebulous question.

You could be asking about if it's true. In that case, you should build it yourself and run some tests, since it might or might not be true for your requirements.

Or you could be asking about the author of that fork. He was a long time developer at CCP, and worked on low-level details of the Python and Stackless Python implementations. Eg, he made changes so that Python could fit into consoles, like the Playstation. But the internal evidence in the blog post looks solid, so I don't think you really need to consider reputation as well - download the code and test it out.

Personally, my thoughts are "hey, I didn't realize Kristján left CCP. I wonder what he's doing now. I haven't seen him for years. I should visit Iceland again."

But I suspect those weren't the thoughts you were looking for.
