The experience with PEP 563 shows that string annotations make things much more difficult for dataclasses and other users of runtime type annotations. The point of PEP 649 and the forward declaration of classes is to make it possible to remove string annotations entirely.(That said, my personal opinion is that this is pretty heavyweight for very little gain; why not just create a placeholder class that static analysis tools are supposed to recognize as likely-to-be-replaced later? And why not just use strings giving the expected eventual class name? It isn't as though the analysis can verify whether something actually meets the full intended contract before they've also parsed the continuation.)
