Description
I'm not sure if I should open an issue here at typing, please let me know if there is something better.
WSGI type defines. https://gist.github.com/abersheeran/f3723029387fe7f6584c6b157b90a50a
When writing a more static WSGI definition based on PEP3333, I discovered such a problem. TypedDict cannot describe the HTTP_* keys in the WSGI specification. I know that one of the original intentions of TypedDict is to prevent typing the wrong keys. But can we add an option (for example: allow_undefined=True) to allow this actual problem?

Research direction
Start by reviewing TypedDict behavior and the WSGI type definition in the linked gist, using PEP3333 as the requirements reference. Determine whether supporting HTTP_* key names needs a new option or another typing design, then confirm the proposal with the typing maintainers; done means an accepted approach with corresponding tests or documentation identified.
