Having worked with Asynchronous python since the days of twisted, tornado - I haven't really found any real reason to switch to asyncio. Generally speaking the old forms of async syntax (@coroutine, @inline_callback) make it incredibly clear that you are executing code well outside of a sequential paradigm - they force you to think a little more about what is going on. The idea of Django throwing errors when you try and run async unsafe code within an event loop gives me cause for concern. I can just imagine folks who don't understand adding 'yield', 'await', 'yield from' until the errors go away - while being confused with the resulting execution. I think there is always a place for synchronous code in Python - I think Django should lean in to the simplicity afforded by it. Last note - I also am very weary to mix asynchronous code with other primitives like threading, multiprocessing. If I am going the route of async programming - I usually just intend to optimize a single thread - and then I leave it up to the OS to optimize across multiple processes.
