The problem I've seen is that the opinion of code formatted with 3 lines
of context can differ from 5 lines of context which can be still
different again given the entire file. The only reliable way we've
gotten it to work is to format the whole file every time. But we require
well-formatted code via CI processes, so that's fine (if one can afford
the "rewrite the world" every time the tool gets updated…hence why some
projects are still on version 3.8(!), others 6, some even made it to 9).
