This seems non-trivial to fix; even if some other event loop policy 
might work, the whole event loop policy system is deprecated and will be 
removed in Python 3.16 according to 
https://docs.python.org/3/library/asyncio-policy.html, so this really 
needs an active upstream maintainer to do whatever redesign is 
appropriate.  Unfortunately, there've been no upstream commits for over 
three years (see also https://github.com/aio-libs/aiozmq/issues/191).

I don't see any reverse-dependencies in Debian, so I wonder if it's time 
to just remove this package?  CCing the Python team and Piotr (who 
originally added this package) for second opinions.

Thanks,
