The typing-related PEP 645 - which introduces the syntax `T?` to mean `Optional[T]` - only has a single substantial related commit in the PEPs repo - the commit introducing the PEP (in Nov 2020) - and no discussions thread that I can find (on typing-sig or elsewhere).
I'm personally quite interested in the potential capability to quickly signify `Optional[T]` since it is something I do a lot.
What is the status of this PEP? Deferred for now? Withdrawn in favor of `T|None` syntax?† Something else?
