@marcan@treehouse.systems as a maintainer, I prefer separate commits for separate things. But I also understand it's not always practical and asking for a change is not always worth burdening the contributor. So instead, I might say "alright, this one is fine but I'd prefer this other way next time". It's not a dealbreaker if that commit isn't perfect.
Also, I make sure everything is mechanically formatted and if it isn't, CI fails. It's just not worth having discussions about.
