No, we can't. What you are proposing would make it very hard for users to understand at a glance if what you have in an innocently looking `except Exception` is correct or not. In my async/await code I'd have to always check the `__group__` attribute to make sure it's not an exception group in disguise. So while you're "simplifying" the proposal by removing a couple of types, you're complicating it in all other places. Besides, I don't think that adding the ExceptionGroup type is a controversial idea that needs any simplification.
