`mount` is not the same as `mount -o degraded,rw`. The latter should raise the eyebrows of anyone paying attention to what they're typing. Odds are that you'll have to consult the docs to even find these mount options, because it doesn't happen automatically. This is where any careful, sane user who's concerned about their data would spend a few more minutes thinking through their entire recovery procedure.
There's one corner case to RAID1 recovery where the current tooling does not fully prevent a careless user from putting the FS in a bad state. This is not the same as "RAID1 doesn't work right".
