I did a a cursory investigation using GitHub search and also looked at
a big internal codebase, and a significant fraction of callsites used
a dict type instead of a TypedDict or a dict literal.
It seems that it's a common use case to store the config within an
attribute. For example, something like this:
```
CONFIG = {
...
}
...
logging.config.dictConfig(CONFIG)
```
Another use case that was not properly supported is reading the
config from a file, and the config is given `dict[str, Any]` as
the type.
Mypy can still do some type checking of the argument if called
with a dict literal, so I feel this is a reasonable compromise
between type checking strictness and usability.
