If the property never occurs, I would prefer to remove it entirely to avoid having properties that are "lost to time" in the schema.

DioException (DioException [unknown]: null

Could not create `LimitedWorld`.
There is a problem with "storeId".
Required keys are missing: storeId.)

Fair enough, if they come back I suppose we'll just readd them

This is the result before this pr, I added storeId as a required argument because it seemed to always be there, but then they removed it, so now you get "required arguement is missing", hence we're removing it again
