asyncio.iscoroutinefunction should be deprecated in favor of inspect.iscoroutinefunction, we don't need two different functions to do the same thing. I propose to deprecate asyncio.iscoroutinefunction because IMO these introspection functions don't belong to asyncio but more to inspect module. It will be deprecated in Python 3.14 and scheduled for removal in Python 3.16.
