I don't recall hearing this. I remember his agreeing with the idea of
slimming down the SCSI mid layer, which does rather contradict the use SCSI
for everything approach.

After the Kernel Summit, there was quite a long thread on l-k with Joerg
Schilling on exactly this issue. The upshot of which was I clearly said we
weren't going to go the SCSI is everything route. Unless there's any reason
to change course, I think that's the current plan.
