I wish it would. Most of the research and stuff so far has either put
the file system into the disk firmware (upgrade hell). Having a disk
which talked entirely about

read(handle,offset, length)
write(handle, offset, length)
alloc(handle, near_handle, length, otherhints...)

might well work out rather better. It also allows the disk to do fairly
major relayout of data as it learns usage.
