The same information is already available in the file system's own data structures; it shouldn't be necessary for the RAID layer to do that for itself. _That_ kind of redundancy isn't what RAID is supposed to be about.
But yes, there are always band-aids which can help to improve any design flaw.
I rather like the separation between file system and raid devices. It gives more choice and makes both components simpler. Now I can choose raid1+ext2, raid5+ext3, swap+raid0 and reiser+device.
I would rather like not to loose those options. Otherwise it would be like combining "uniq" & "sort", because you could make one case work better.
