No subinterpreters in 3.11 ? If we had those, all this async idiocy would go away, no more code colours, no more single-core, even better isolation and protect

No subinterpreters in 3.11 ? If we had those, all this async idiocy would go away, no more code colours, no more single-core, even better isolation and protection against context-switching tangles. (the implementation not so nice though. Python threads on machine threads ? Whose stupid idea was that ?)
