I say I’m talking about cases where you can’t use f-strings and you directly talk about f-strings… I think you might have missed the point.

Sure. Run this script against django: https://gist.github.com/boxed/e60e3e19967385dc2c7f0de483723502 <https://gist.github.com/boxed/e60e3e19967385dc2c7f0de483723502>

It will print all function calls that are positional and have > 2 arguments. Not a single one is good as is, all would be better with keyword arguments. A few of them are pass through as discussed before, but far from all. 

For example:

django-master/django/http/multipartparser.py 225
                                    field_name, file_name, content_type,
                                    content_length, charset, content_type_extra,

That’s positional because keyword is more painful.
