Actually, I don't think it is.  CCD should be relying on information stored
in a private area of the disk to determine what stripe sets what partitions
belong to, etc.  This is how all of the industrial strength filesystem VM
systems work.  When you open the partition, you see it has a CCD block 
on it, and then pass it on to CCD informing it of the dev that the block
came from.  The upside to this is that you can re-arange your disks (even
put them on different controllers) and the system still finds your array
and makes it work.  Having my root FS on a RAID 5 device makes it
more robust than having it on a single disk. This is more than enough
justification for allowing you to do this.
