No, there are no hidden dangers. --assume-clean is generally quite safe with mirroring levels (raid1, raid10). The only issue is that if you do a regular 'check', then it will reports lots of issues. If do a 'repair' it will fix the issues. With raid4/5/6, --assume-clean is *not* safe if there is any doubt that the drive are not already in an in-sync state.
