Anyone against making a statement that "PEP 563 will never be the default behavior"?
I think only the SC is empowered to make such a statement.
Then, we do not need to decide "PEP 563 or 649". We can focus on whether we can replace "stock semantics + opt-in PEP 563" with PEP 649 or not.
I doubt the current status quo--keeping PEP 563 as optional behavior, permanently--is viable long-term. It causes problems for most runtime uses of annotations, which we were collectively basically ignoring until now. As runtime use of annotations /and/ typing both become more pervasive, these problems are only going to grow. //arry/
