It looks like it's just an alternative python run-time that's small. Seems like the kind of thing you would use for specific resource constrained projects.

I don't think it makes sense for me here though. I wouldn't want people to have to learn about an alternative python distribution just to use the CLI, and 10mb isn't that big all things considered. Is rather have fewer apparent dependencies. I don't see anything about generating small executables with it yet from my search.
