Therefore I'm reassigning this bug to systemd. Nope, there's no place for '\r' in logs. It only makes sense on a console, where you show something and then erase it some time later when the situation changes. Log file viewers don't show logs in real time, so any usage of erase characters should be replaced by simply logging the final version in the first place.
