IMHO the answer is no, because dmpartx (or whatever it's called) can do 
this today. It can use dm tables to slice up any existing block device, 
whether it's a raw disk or a dm-constructed RAID set.

Personally I would be thrilled to see this work move ahead; in fact, I'd 
be happy to see this dmraid tool support the Linux MD metadata so I can 
use dm targets for my MD RAID-1 systems (thereby reducing the amount of 
code I build into my kernel).
