https://docs.python.org/3/library/asyncio-eventloop.html#error-handling-api  

Here we can read:  

Application developers should typically use the high-level asyncio functions, such as asyncio.run(), and should rarely need to reference the loop object or call its methods. This section is intended mostly for authors of lower-level code, libraries, and frameworks, who need finer control over the event loop behavior.  


So as I understand this - I should not use  
asyncio.get_running_loop  
loop.set_exception_handler(...)  

Or maybe event loop should not be in "Low level api"  ???
