> Well, I'm basically using a run method defined as a shorthand for self.loop.run_until_complete (without closing loop, reusing it throughout). It would be nice if asyncio.run could simply be used instead, but I understand you're saying this is easier said than done, which is fine with me. Thanks.

Yes. `asyncio.run()` is similar to `loop.run_until_complete()` but adds some guarantees + sane setup/cleanup. If we strip proper cleanup then there's no point in `asyncio.run()`.  So using `loop.run_until_complete()` is totally fine when you want to preserve the event loop between runs.
