> Unfortunately this has a serious downside: asyncio locks are associated with the loop where they were created. Since the lock variable is global, maybe_initialize() can only be called from the same loop that loaded the module. asyncio.run() creates a new loop so it’s incompatible.

I work on several async projects, but I never had to use multiple event loops. What are use cases for using multiple event loops?

There may be other use cases, but it can be a useful pattern for mixing async code into a non-async project. In the specific places where using async for some task makes sense, you would just spawn a thread with an event loop, then push work into the new loop from non-async code using run_coroutine_threadsafe.
