Absolutely.

Yes very. It's not in there for the fun of it.

If the RAID is shut down unclean, the RAID system will reconstruct the RAID.
If the filesystem is shut down unclean, fsck will fix that.
There's no connection between what you have in /proc/mdstat and the status
of your filesytem. (Except that maybe, if your RAID was unclean, your
filesystem is too. You don't know about the filesystem, even if the RAID
is clean).

Very wrong.
