That's weird. Maybe run them again? We can look into increasing timeout for that run or excluding those

Merged, thanks.

I decided to no longer wait for@1st1 or@asvetlov since they seem to be busy. The change looks reasonable.

If this change breaks too many asyncio project, we can consider to revert it, help projects to migrate, and reschedule the removal once enough projects migrated. I hope that in 2021, most projects are now written with "async def" and "await". The@coroutine syntax is a legacy of Python 3.4-3.5 era. I know that one of reasons why Instagram migrated from Python 2.7 to 3.6 is to getasync def syntax!

@vstinner did this miss the deadline for py3.10 backport?

Thanks@vstinner &@graingert!

This removal was discussed shortly before the 3.10 feature freeze. Victorsuggested to wait for Python 3.11 to remove the decorator.
