I think with the Black formatter you can force the multiline version by adding a trailing comma to the arguments.

The pain point you describe is real, which is why that was intentionally added as a feature.

Of course it requires a language that allows trailing commas, and a formatter that uses that convention.

A similar tip: As far as I can tell, clang-format doesn't reflow across comments, so to force a linebreak you can add a // end-of-line comment.
