PEP-692 was accepted, but without the syntax change. That means there's very little to do in CPython, but a few changes should be made:

• https://docs.python.org/3.12/library/typing.html#typing.Unpack should mention this new use for Unpack
• https://docs.python.org/3.12/whatsnew/3.12.html should mention the PEP
• Maybe some aspects oftyping.py assume Unpack is only used for PEP 646 and should be updated

And maybe something else I'm forgetting.
