It is a RAID level, now.  It wasn't in the original paper since it lacks the 
*R* in RAID--Redundancy.

LVM can also do striping, but it can't non-orthogonally combine it with RAID 1 
to give me RAID 1/0.

On the other hand, LVM striping is per-LV.  Doing something like that with 
mdadm is... complex.
