I would disagree on the first paragraph, if only to say that the majority of Python stdlib documentation is written in that tutorial style, and I loathe it. It is always a chore to look something in the stdlib up, especially if you're used to the reference documentation for Rust/Go/Ruby/JavaScript.

I think a lot of standard library have both. For example multiprocessing or logging. It's true, the tutorial is annoying, except perhaps on first reading, but at least the proper documentation is there. For asyncio the actual hard documentation bit is missing, incomplete or misleading, depending on where exactly you're looking.
