The documentation says:

  .. deprecated-removed:: 3.7 3.9

     Do not call this as a task method. Use the :func:`asyncio.all_tasks`
     function instead.

I don't know if it's still possible to merge this in 3.9 and if so, if it should be a release blocker. Anyway I'm working on a PR for this.

Thanks for bringing attention to this Rémi.

I'm a bit concerned that it might be a bit late into the 3.9 beta to incorporate a removal and that we might need to consider delaying to 3.10, but I'll leave that up to Lukasz. Feel free to open a PR in the meantime since it will need to be removed either way, the only main difference is whether or not it gets backported to 3.9.

(I elevated the priority to "release blocker", as I think it should be a blocker for 3.10 if it's not for 3.9. The version should be updated accordingly.)

[remilapeyre]

With beta 4 coming in 2 days it would perhaps good to choose now whether this must be done for 3.9 or 3.10

Agreed. I'm definitely leaning towards 3.10 with it being decently well into the beta, but I'll try to bring this to Yury's attention to make a final decision on the matter. Optimally, we want to do removals before the beta so that users can prepare accordingly rather than deal with breakage in the final release.

+1 to remove it now. Up to Lukasz to give us green or red light here, though.

Go ahead.
