1. How about we support NotRequired[...] in general?
2. How do folks feel about *also* supporting Required[...] for when a 
total=False TypedDict really is more appropriate?
As a quick followup comment: If we were to support both NotRequired[...] 
and Required[...] it would translate well to the proposed eventual 
shorthand + and - syntax for these wrappers:

```
class MyThing(TypedDict, total=False):
     req1: +int    # + means Required[...]
     opt1: str
     req2: +float

class MyThing(TypedDict):
     req1: int
     opt1: -str    # - means NotRequired[...]
     req2: float
```
