Thanks Matthew! Merged PRs can still be reverted, and we have some time before the feature freeze. I'd like to hear what Guido and Ken think too. If we go with the GenericAlias substitution, we need to make sure that such aliases still work as base class. That would need some C work to make types.GenericAlias.__mro_entries__ recurse if the alias's origin is itself a GenericAlias. There's a few other subtleties to think about; I can work on that but don't have a ton of time today.
