I’m generally pretty happy with the status quo, but would like to remove unchecked annotations (the multiprocessing example you link isn’t even a valid type hint!)
I’d previously written a longer post here Type annotations in the stdlib - #7 by hauntsaninja that might help provide some context to those who weren’t in the room for this consensus:
Consensus in the room […] seemed to be that there’s still not much to be gained from having type annotations in more of the standard library.
