the fact that the linux raid code isn't suitable for most raid hardware is true, but I disagree with the rest of your points.

most 'hardware' raid cards don't support raid level migration, in fact most don't even support raid resizing (wihc MD does support)

MD does support swapping disks (it doesn't do it automagicly, but you can remove and replace drives in a MD array just fine)

I would be surprised to see linux running on a raid card.

but I would not be surprised to see linux running on a external raid box. the type of thing that allows you to connect a bunch of SATA drives to it and exports the results as a single drive via SCSI or FC.

for this to work well the target mode will need to get into the kernel and get well tested first.
