This is nitpicking, I never said that. There is still no explanation for what "mess" means, but I don't think it means having multiple competitors providing an implementation. The fact that there are multiple async Python libraries means that the internals are generic enough to allow that. From what I understand of Rust, there could be another "tokio" as well. And they would not necessarily be compatible either. This is like saying "You can't use a Django model with SQLAlchemy".
