OK, as I predicted, situation for protocols is much better, but there is still some fallout, and I am afraid there may be situations like in One thing to help with the situation is to add some kind of a note if subtype has positional-only arguments, while supertype doesn't have any. Otherwise it is hard to spot Anyway, I will leave up to @JukkaL when to merge this. Technically, we don't need to do this is in a major release, since this was a clear false negative. But we should probably still avoid batching too many potential breakages in a single release. |

In the upcoming release we are dropping 3.7 support, and then once master unfreezes we can use PEP 570. Should help here. |
