as a user following the potential inclusion of a kernel-space target,
iscsi specifically, I would be very interested in seeing what other
pluses the other frameworks have over scst, because if this chart is
accurate, all the other targets have quite a ways to go to catch up.

To me, lacking correct reserve and task management means "not ready
for public consumption".  Making any kernel change that does not have
RESERVE/RELEASE and full TM command support is only going to make
Linux look buggy and amateur-ish in the storage world.  Best to not
change anything than to implement something without them.  These 2
features alone are what helped me choose SCST in the first place.
