A single isolated case can do anything.

I think they are proposing a language for a multitude of kids, I assume to be thought in schools. Applied to their case, I don't think what you say here works, i.e. you can't teach that to a class of 10-30 kids.

You need to find something which is "ok" (whatever that means) for the average kid. And that's why I was expressing my concerns about the parentheses.
