This break the "layer" model. i have 3 layer : raid, volume management, and fs (Can Swap the two first). If one of them is upgraded or replace by another, no problem. This also respect the unix philosophy : do a single thing, but do it well. Computing had always used layer model (network...). Because it's good and reliable. And for me, keeping my data safe is the most important thing.
