It's quite enjoyable to watch, but obviously it's not scalable or sustainable in the general case.

That seems fair, yes.
My personal view is that there's about a 90% chance the project will collapse under its own weight before it ever hits a release and becomes a normal project, but there's a 10% chance it'll (one day) migrate into a real language (with a real governance model, an actual team working on it, bugfixes being shipped, etc.).
