I really don't follow you. You say, yes, there is need for more,
block-device-level support for this functionality. Then you go on to
say that the existing implementation which has NO block-device support
requirements has all sorts of extra advantage.
I don't understand! Are you in favour of doing it this way, in the
filesystem, using multiple filesystem extents (like I am), or in favour
of hiding all of that detail in a block device LVM system?
