> For asyncio.Lock (plus other synchronization primitives) and asyncio.Queue, this would be added in https://github.com/python/cpython/pull/18195. Currently waiting on emanu (author of the PR) to finish up some changes, but it's mostly complete. Could I work on adding it to asyncio.Future and other classes in the meantime?

I think the approach should be different:


  # leading underscore is significant:
  loop = asyncio._get_running_loop()  
  if loop is None:
    issue_deprecation_warning()
    loop = asyncio.get_event_loop()
