Non-blocking HTTP requests is an extremely common need, for instance. Why the hell did we need to reinvent special asyncio-aware request libraries for it? It's absolute madness. Thread pools are much easier to work with.

This is both not really true and also irrelevant. When you need a flask (or whatever) request handler to do parallel work, asyncio is still pretty bullshit to use vs threads.
