As I said in Please consider delaying, or even rejecting, PEP 695 - #2 by AlexWaygood, I feel pretty strongly that doing PEP 695 before PEP 696 is the wrong order in which to do things. If done before PEP 695, PEP 696 does not require any syntax changes in and of itself.
I’ll be pretty sad if PEP 695’s acceptance means that we will lose the ability to easily introduce new features into the typing system without introducing new syntax changes.
