I've seen the reason, I just don't find it convincing. I would like to omit these commas, but also use the formatter sometimes, but that's not really an option. It's frustrating since 'uv format' will omit them for older python versions, so the logic is there.

Something between "everything fits on one short line" and "every argument gets its own line" would be nice too. Spreading a function definition or call across ten lines when it would fit on two or three doesn't feel like an automatic win.
