--force was added for a different reason, to allow check on a mounted filesystem. I don't think that combining --repair and --force just to allow repair is a good idea. There's a 'dangerous repair' mode for eg. xfs that allows to do live surgery on a mounted filesytem (followed by immediate reboot). We want to be able to do that eventually. I understand where the motivation comes from, let me have a second thought on that.
