Consider the best practice for getting class annotations, example here from Lib/dataclasses.py:

    cls_annotations = cls.__dict__.get('__annotations__', {})

Isn't that going to get broken anyway? It won't trigger the
calling of __co_annotations__.

I proposed these as two separate conversations, because I wanted to clean up the semantics of annotations whether or not PEP 649 was accepted.  But, yes, if PEP 649 is accepted (in some form), this current-best-practice would no longer work, and the new best practice would likely become much more complicated.
